664–673. "Woodpecker" Duga radar array, Chenobyl, Ukraine by Necator Woodpecker - Woodpecker on shortwave radio interfering with WWVH, November 2, 1984. (1 January 1974). Thirty years on, what do we know? It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name.The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility … Ever hear of the 'Woodpecker Hunters Club'. But it was obvious to any observers that the signals were coming from more than one source over Russia. AKA Woody Woodpecker. One idea amateur radio operators used to combat this interference was to attempt to "jam" the signal by transmitting synchronized unmodulated continuous wave signals, at the same pulse rate as the offending signal. The Russian Woodpecker was a notorious Soviet signal that was heard on the shortwave radio bands worldwide between July 1976 and December 1989. The screen somewhere in Russia blanks out and the operators utter some Russian oaths and change the frequency to get rid of the interference." It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name. Unknown to civilian observers at the time, NATO was aware of the new installation[citation needed], which they referred to as Steel Yard. You can still visit the existing The Russian Woodpecker arrays today but as it is located in within the Chernobyl Exclusion Zone, permits need to be obtained in advance. In the early 1970's the first Duga radars appeared. The Soviet Union also never officially acknowledged the arrays. The system operated… Russian Woodpecker - … : Artech House, 1987]. has a plot focused on the Chernobyl Nuclear Power Plant and the nuclear accident there. They also claimed that these low-frequency “Russian ‘woodpecker’ signals” could destroy human brain cells and or control human behaviour. The purpose of these arrays was to allow the Soviets to detect any incoming ballistic missiles from America and European NATO members. They appeared without warning, sounding like a sharp, repetitive tapping noise at 10 Hz, which led to it being nicknamed by shortwave listeners the ‘Russian Woodpecker’. Deep in the radiated Chernobyl Exclusion Zone in the Ukraine stands the abandoned Duga radar, a mysterious piece of Soviet Cold War technology also known as the "Russian Woodpecker." They appeared without warning, sounding like a sharp, repetitive tapping noise, which led to it being nicknamed by shortwave listeners as ‘Russian Woodpecker’. It became such a nuisance that receivers began to include "Woodpecker Blankers" in their circuitry to attempt to filter out the interference. The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. The Ukrainian-developed computer game S.T.A.L.K.E.R. The signal was observed using three repetition rates: 10 Hz, 16 Hz and 20 Hz. A backplane reflector of small wires can just be seen left of center, most clearly at the bottom of the image. The array itself appears in STALKER: Clear Sky in the city of Limansk-13. 2. [4] This sequence is usable for a 100 μs chirped pulse amplification system, giving a resolution of 15 km (10 mi) (the distance light travels in 50 μs). They appeared without warning, sounding like a sharp, repetitive tapping noise at 10 Hz, which led to it being nicknamed by shortwave listeners the Russian Woodpecker. Woodpecker (engl. The random frequency hops disrupted legitimate broadcasts, amateur radio operations, oceanic commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. In this background, the United States Federal Communications Commission (FCC) held a study in 1988 on the ‘Woodpecker’ signals. With this so prominently displayed, it’s possible to confirm that the signal is not a "Dead Man’s Switch," nor is the signal intended to be a secret. The tapping noise could also be heard over telephone circuits at times because of the strength of the signal. Das Überhorizontradar (auch OTH für Over The Horizon genannt) stellt eine Möglichkeit dar, Radarechos ohne quasi-optischen Sichtkontakt weit über die Erdkrümmung hinaus zu erhalten.

Data analysis showed an inter-pulse period of about 90 ms, a frequency range of 7 to 19 MHz, a bandwidth of 0.02 to 0.8 MHz, and typical transmission time of 7 minutes. Coordinates: 51°18′16″N 30°03′53″E / 51.3045404°N 30.0647736°E / 51.3045404; 30.0647736. Except for the possibility of some level of tropospheric ducting, microwave frequencies (3GHz through 3000GHz frequency, 10cm through 0.1 mm wavelength) are basically line-of-sight. These arrays were truly enormous. Duga-3 could operate not on a 'single' frequency but on a wide range of frequencies (my memory says approximately 5MHz through 20 MHz, but likely a bit further - one had to adapt to constantly changing ionospheric propagation conditions, after all). It consisted of over three hundred individual transmitter elements. Woodpecker on shortwave radio interfering with.

"Over-the-Horizon radar in the HF band". Sep 05, 2012 It is extremely obvious that the 'woodpecker' was/is an OTH 'radar' operating down on the Shortwave/HF frequencies instead of the standard microwave frequencies. 2. [58], On July 15, 2020 a Voice message of unknown origin was heard on 4624.2 kHz, just below the Buzzers frequency. Digital object identifier: Headrick, James M.; Skolnik, Merrill I. Bureau d’Etudes (2005) Anderson, Jack. However, after careful study, many experts and amateur radio hobbyists long believed it to be that of an extremely powerful over-the-horizon radar (OTH) system. The Soviets had been working on early warning radars for their anti-ballistic missile systems through the 1960s, but most of these had been line-of-sight systems that were useful for raid analysis and interception only. According to some reports, the Komsomolsk-na-Amure installation in the Russian Far East was taken off combat alert duty in November 1989, and some of its equipment was subsequently scrapped. Headrick, James M. (1 July 1990). Several other theories were floated as well, including everything from jamming western broadcasts to submarine communications. By subscribing, you agree to our Terms of Use and Privacy Policy. uga (Russian: Дуга) was a Soviet over-the-horizon (OTH) radar system used as part of the Soviet anti-ballistic missile early-warning network. The Russian Woodpecker Not an avian at all, the Russian Woodpecker was the vast, faceless and distant enemy of most of the users of shortwave radio in the Western World for eight or nine years, beginning in 1976. The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. [58], On July 15, 2020 a Voice message of unknown origin was heard on 4624.2 kHz, just below the Buzzers frequency. History. The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. pp. “Russian Woodpecker” is the nickname for the infamous low-frequency radio signal, transmitted from 1976 to 1989 from within the Soviet Union, which disrupted international communications with its random frequency hops. Folks were going about their electronic business in North America one day (July 4, 1976. Die zufälligen Frequenzwechsel störten den öffentlichen Rundfunk sowie Funkamateure, was weltweit zu tausenden… Russian Woodpecker signal . This interference permeated the airwaves and disrupted over air communications and television signals all over the world. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name. RUSSIAN RADAR a.k.a. The Lawrence Livermore National Laboratory located at Livermore, CA was and is the main research center for US development of the Project. It is extremely obvious that the 'woodpecker' was/is an OTH 'radar' operating down on the Shortwave/HF frequencies instead of the standard microwave frequencies. Even from the earliest reports it was suspected that the signals were tests of an over-the-horizon radar,[3] and this remained the most popular hypothesis during the Cold War. russischer Specht) wurde ein Kurzwellensignal, welches zwischen Juli 1976 und Dezember 1989 weltweit auf kurzwelligen Radiofrequenzen zu hören war. Stream Russian Woodpecker by NATtheKILLERnoob from desktop or your mobile device [12], The Buzzer has apparently been broadcasting since at least 1973[13] as a repeating two-second pip, changing to a buzzer in early 1990. The Woodpecker disappeared in 1989. Text and photos, OTH-Radar "Chornobyl - 2" and Center of space-communication, "Circle" is an auxiliary system for OTH-Radar "Chornobyl - 2", https://military.wikia.org/wiki/Russian_Woodpecker?oldid=5179429. The pulses themselves were of unknown shape and length, as they were hashed by the bounces and the like, but their observed length varied between 3 and 6 ms. As early as 1963, or before, radio amateurs were calling this "the Russian Woodpecker". Bureau d’Etudes (2005) Anderson, Jack. Yet others began to think the arrays were actually used to interfere with the weather or even attempt mind control. The Russian Woodpecker was a notorious Soviet signal that could be heard on the shortwave radio bands worldwide between July 1976 and December 1989. The broadcast jamming theory was debunked early on when a monitoring survey showed that Radio Moscow and other pro-Soviet stations were just as badly affected by woodpecker interference as Western stations. 2015 Sundance Grand Jury Prize Winner – World Documentary. In 1978, various US researchers argued that a signal originating from within the Soviet Union, the so-called Russian Woodpecker, was an experiment in global mind control. Some conspiracy theorists also let their imagination run riot. Conspiracy Times – The Russian Woodpecker: experiments in global mind control? Union. However, playing back recordings of the woodpecker transmissions sometimes caused the woodpecker transmissions to shift frequency leading to speculation that the receiving stations were able to differentiate between the 'signature' waveform of the woodpecker transmissions and a simple pulsed carrier." "The Race for Star Wars Weapons." The Russian Woodpecker was a notorious Soviet signal that could be heard on the shortwave radio bands worldwide between July 1976 and December 1989. During the 1970s and 80s Russia deployed their Over-the-Horizon Radar (OTHR) which ultimately became known as the “Russian Woodpecker” to HAM Radio enthusiasts worldwide. Hello, just curious if anyone else has heard what sounds like the old Russian Woodpecker on the ham bands as of late? Duga-3 could operate not on a 'single' frequency but on a wide range of frequencies (my memory says approximately 5MHz through 20 MHz, but likely a bit further - one had to adapt to constantly changing ionospheric propagation conditions, after all). All of these reports were describing the same deployment, with the transmitter only a few kilometers southwest of Chernobyl (south of Minsk, northwest of Kiev) and the receiver about 50 km northeast of Chernobyl (just west of Chernihiv, south of Gomel). They appeared without warning, sounding like a sharp, repetitive tapping noise at 10 Hz, which led to it being nicknamed by shortwave listeners the Russian Woodpecker. When in use, the Soviets had little regard for which frequency they would use at a particular time but it would range between 3 MHz and 30 MHz. The distinct repetitive tapping noise was broadcast in shortwave radio bands (at a frequency power of over 10 MW in some cases) and quickly became nicknamed by … The nearly half-century Cold War between the United States and Soviet Union produced many strange stories, but perhaps few are stranger than that of Duga, the enigmatic radar array entrenched in the forests of Ukraine.Even some 30 years after finally going silent, the structures remain an enigma, following more than a decade of incessant, mysterious radio interference. Sep 05, 2012 It is extremely obvious that the 'woodpecker' was/is an OTH 'radar' operating down on the Shortwave/HF frequencies instead of the standard microwave frequencies. The secret code name given US operations was Project Woodpecker. As more information about the signal became available, its purpose as a radar signal became increasingly obvious. The nearly half-century Cold War between the United States and Soviet Union produced many strange stories, but perhaps few are stranger than that of Duga, the enigmatic radar array entrenched in the forests of Ukraine.Even some 30 years after finally going silent, the structures remain an enigma, following more than a decade of incessant, mysterious radio interference. Starting in the late 1980s, even as the U.S. Federal Communications Commission (FCC) was publishing studies of the signal, the signals became less frequent, and in 1989 disappeared altogether. The frequency range was 7 to 19 MHz and a bandwidth of 0.02 to 0.8 MHz. Share This Story, Choose Your Platform! In 1988, the Federal Communications Commission conducted a study on the Woodpecker signal. The bro… Starting in 1976 a new and powerful radio signal was detected worldwide, and quickly dubbed the Woodpecker by amateur radio operators. Headrick, James M., Ch. The Russian Woodpecker was a notorious Soviet signal that could be heard on the shortwave radio bands worldwide between July 1976 and December 1989. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the “Woodpecker” name. However, playing back recordings of the woodpecker transmissions sometimes caused the woodpecker transmissions to shift frequency leading to speculation that the receiving stations were able to differentiate between the 'signature' waveform of the woodpecker transmissions and a simple pulsed carrier." The study found that a typical transmission time was 7 minutes. The random frequency … The Washington Post via CIA Reading Room FOIA (1981) Lee, James Franklin, Jr. "The Chernobyl Meltdown and Russian Woodpecker Map" ClimateViewer 3D Globe "The … Some thought it was being used to jam Western broadcasts or even interfere with submarine communications. It sounded like a sharp, repetitive tapping noise at 10 Hz,[1] giving rise to the "Woodpecker" name. Well the signal emitted a sound pattern of its transmitted pulses at HF frequencies that was heard on worldwide shortwave radios to the annoyance of HAM operators. Each array operated at very high power levels, in some cases as much as 10 million watts. While the 'Brain Scorcher' from STALKER: Shadow of Chernobyl was inspired by theories that Duga-3 was used for mind control, it does not take the form of the real array. „Specht“) ist die Bezeichnung für ein sowjetisches Kurzwellensignal, das zwischen Juli 1976 und Dezember 1989 weltweit auf Radiofrequenzen zu hören war.Die zufälligen Frequenzwechsel störten den öffentlichen Rundfunk sowie Funkamateure, was weltweit zu tausenden Beschwerden führte. The Lawrence Livermore National Laboratory located at Livermore, CA was and is the main research center for US development of the Project. The Russian Woodpecker – Trailer. pp. [Editor's Note: This is older information, but a good assessment, nevertheless, of situation in the 1970s and 80's, and an accurate predictor of the far scarier situation in which we find outselves today. So powerful was the device that it would interfere with radio receivers and become known as The Russian Woodpecker. HF/ShortWave/HAM Radio Interference by id780 February 22, 2010. from YouTube Website . Conspiracy Times – The Russian Woodpecker: experiments in global mind control? The secret code name given US operations was Project Woodpecker. (Duga is Russian for arch or bow) The Duga-1 and Duga-2 OTHRs were built near Nikolaeyev in. It was given the nickname based on the sound of the frequency which seemed like the sound of a woodpecker pecking a tree. Home page. Folks were going about their electronic business in North America one day (July 4, 1976. The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility transmissions, and resulted in thousands of complaints by many countries worldwide. Watch the trailer below: The film includes interviews with the commander of the Duga Vladimir Musiets, as well as the Vice-Commander, the Head of the Data Center, and others involved in building and operating the radar. Even prior to 1976, a similar 'woodpecker' interference is remembered by radio amateurs occurring in the high frequencies. NATO military intelligence had photographed the system and given it the NATO reporting name Steel Yard. This "Russian Woodpecker" was a set of massive arrays of antennae constructed in secret in woods close to Chernobyl in Ukraine. A couple months ago I head what sounded a lot like the audio clips I have heard of the infamous signal on 40m band late at night. Thirty years on, what do we know? Die verwendeten Frequenzen liegen meist im Kurzwellenbereich und damit weit unterhalb der üblichen Radarfrequenzen (Mikrowellenbereich), dadurch sinkt die Auflösung und die Ortungsgenauigkeit. In static mode, the woodpecker would transmit four pulses, one on each of the four operating frequencies, in four adjacent 7 ms windows. But surprisingly, the signals became less frequent. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name. Not only that but the technology had quickly become obsolete and was replaced by more accurate satellite-based warning systems. The Washington Post via CIA Reading Room FOIA (1981) Lee, James Franklin, Jr. "The Chernobyl Meltdown and Russian Woodpecker Map" ClimateViewer 3D Globe "The … When a second array was built in Eastern Russia it became obvious it was some form of detection system pointed towards the US. The pulses transmitted by the woodpecker had a wide bandwidth, typically 40 kHz. Russian Woodpecker signal . Russian radar - Over the horizon radar (ABM-2 or 'DUGA-3' OTHR). Why that moniker? Some sources say the signal was renewed in 2014. During the 1970s and 80s Russia deployed their Over-the-Horizon Radar (OTHR) which ultimately became known as the “Russian Woodpecker” to HAM Radio enthusiasts worldwide. Duga-3 array within the Chernobyl Exclusion Zone. Several other theories were floated as well, including everything from jamming western broadcasts to submarine communications. Two operational Duga radars were deployed, one near Chernobyl and Chernihiv in the Ukrainian SSR (present-day Ukraine), the other in eastern Siberia. In 1978, various US researchers argued that a signal originating from within the Soviet Union, the so-called Russian Woodpecker, was an experiment in global mind control. Fundamentals of Over-the-Horizon Radar (translated by W. F. Barton) [ Norton, Mass. A small, framed piece of paper in an administration and enlistment office of the Russian army refers to 4625 kHz, the broadcasting frequency of UVB-76. Als Russian Woodpecker (engl. The arrays were built by the Soviet Union to provide an early warning radar system called Duga. A., ed. They formed a club called The Russian Woodpecker Hunting Club.[5]. This characteristic tapping sound gave the device(s) its now-famous nickname "The Russian Woodpecker" aka the Duga Radar system. Another factor was the success of the US-KS early-warning satellites, which entered preliminary service in the early 1980s, and by this time had grown into a complete network. Even from the earliest reports it was suspected that the signals were tests of an over-the-horizon radar, and this remained the most popular hypothesis during the Cold War. The original Duga-3 site lies within the 30 kilometer Zone of Alienation around the Chernobyl power plant. Hams, from the earliest woodpecker days, have been driving the monster off their bands by getting on the frequency and sending properly spaced dots back. The Russian Woodpecker: Experiments in Global Mind Control? It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name.The random frequency hops disrupted legitimate broadcast, amateur radio, commercial aviation communications, utility … Stream Russian Woodpecker by NATtheKILLERnoob from desktop or your mobile device [12], The Buzzer has apparently been broadcasting since at least 1973[13] as a repeating two-second pip, changing to a buzzer in early 1990. [New York: McGraw-Hill, 1990]. Share This Story, Choose Your Platform! Duga-3 Russian language: Дуга-3 (NATO reporting name Steel Yard) was a Soviet over-the-horizon (OTH) radar system used as part of the Soviet ABM early-warning network. Why that moniker? 2015 Sundance Grand Jury Prize Winner – World Documentary. 36–39. The Russian Woodpecker was a notorious Soviet signal that was heard on the shortwave radio bands worldwide between July 1976 and December 1989. Duga (Russian: Дуга́, literally "arc" or "curve") was a Soviet over-the-horizon radar (OTH) system used as part of the Soviet missile defense early-warning radar network. "The Russian Woodpecker (infographic)." During the 1970s and 80s Russia deployed their Over-the-Horizon Radar (OTHR) which ultimately became known as the “Russian Woodpecker” to HAM Radio enthusiasts worldwide. The Russian Woodpecker was a notorious Soviet radio signal that could be sporadically heard on the shortwave radio bands worldwide between July 1976 and December 1989. Two arrays were built near Chernobyl with a third located on the Russian Pacific Coast near Sakhalinsk. (Duga is Russian for arch or bow) The Duga-1 and Duga-2 OTHRs were built near Nikolaeyev in. Closer analysis of the signals revealed a pseudo-random binary sequence that gave the radar a resolution of around 15km. It is extremely obvious that the 'woodpecker' was/is an OTH 'radar' operating down on the Shortwave/HF frequencies instead of the standard microwave frequencies. A Ukrainian victim of the Chernobyl nuclear disaster discovers a dark secret and must decide whether to risk his life by revealing it, amid growing clouds of revolution and war. The system operated from July 1976 to December 1989. [citation needed]. [citation needed] Triangulation quickly revealed the signals came from Ukraine. When listened to on a normal receiver, the pulsing signal made a "bup-bup-bup" sound compared variously to a machine gun, a helicopter, or of course a woodpecker. Starting in 1976 a new and powerful radio signal was detected worldwide, and quickly dubbed the Woodpecker by amateur radio operators. The Russian Woodpecker – Trailer. 24: "HF over-the-horizon radar," in: Radar Handbook, 2nd ed., Merrill I. Skolnik, ed. The Russian Woodpecker is a Soviet-era anti-ballistic missile system that remains in current day Ukraine. It appears to have been permanently deactivated, since their continued maintenance did not figure in the negotiations between Russia and Ukraine over the active Dnepr early warning radar systems at Mukachevo and Sevastopol. Confusion due to small differences in the reports being made from various military sources led to the site being alternately located near Kiev, Minsk, Chernobyl, … The most common rate was 10 Hz, while the 16 Hz and 20 Hz modes were rather rare. The antenna still stands, however, and has been used by amateurs as a transmission tower (using their own antennas) and has been extensively photographed. The system fell out of use in 1989 as the Cold War came to a close and the Soviet Union finally collapsed. "Looking over the horizon (HF radar)". Some sources say the signal was renewed in 2014. Russian Woodpecker was a high-powered over-the-horizon radar system which used HF (also known as shortwave) frequencies in the 70s/80s. Covert funding for the Project was funneled through the CIA and the National Security Agency. When a second Woodpecker appeared, this one located in eastern Russia but also pointed toward the US and covering blank spots in the first system's pattern, this conclusion became inescapable. The Russian Woodpecker: Experiments in Global Mind Control? The Russian Woodpecker was a notorious Soviet radio signal that could be sporadically heard on the shortwave radio bands worldwide between July 1976 and December 1989. One of the Chernobyl ones measured 210 meters wide by 85 meters tall. The interference was accordingly dubbed the Russian Woodpecker, as amateur radio enthusiasts quickly triangulated the source to an area in what was then the USSR (in the modern day this is in the “three-corners” region where Ukraine, Belarus, and Russia meet). Triangulation quickly revealed the signals came from Ukraine. Because of its extremely high power output (over 10 MW in some cases), the signal became such a nuisance that some receivers such as amateur radios and televisions actually began including 'Woodpecker Blankers' in their design. The Russian word "duga" means "arc" in English. The array of pairs of cylindrical/conical cages on the right are the driven elements, fed at the facing points with a form of ladder line suspended from stand-off platforms at top right. The satellite system provides immediate, direct and highly secure warnings, whereas any radar-based system is subject to jamming, and the effectiveness of OTH systems is also subject to atmospheric conditions. "The Russian Woodpecker (infographic)." [Editor's Note: This is older information, but a good assessment, nevertheless, of situation in the 1970s and 80's, and an accurate predictor of the far scarier situation in which we find outselves today. This led to them being able to completely drown out legitimate transmissions over the same frequency, hence the characteristic interference on people's radio sets. The Russian Woodpecker was a notorious Soviet signal that could be heard on the shortwave radio bands worldwide between July 1976 and December 1989. They could not, however, be entirely sure what it was being used to scan for. This theory was publicly confirmed after the fall of the Soviet Union, and is now known to be the Duga-3 (Russian language: Дуга-3)[2] system, part of the Soviet ABM early-warning network. Little is apparently known about the power levels or Russian designation but is probably a forerunner of the Duga radar systems. Covert funding for the Project was funneled through the CIA and the National Security Agency. The Woodpecker disappeared in 1989. Union. The system operated from July 1976 to December 1989. During the 1970s and 80s Russia deployed their Over-the-Horizon Radar (OTHR) which ultimately became known as the “Russian Woodpecker” to HAM Radio enthusiasts worldwide. You may unsubscribe at any time. The Russian Woodpecker Not an avian at all, the Russian Woodpecker was the vast, faceless and distant enemy of most of the users of shortwave radio in the Western World for eight or nine years, beginning in 1976. It sounded like a sharp, repetitive tapping noise, at 10 Hz, giving rise to the "Woodpecker" name. The Russian Woodpecker was the nickname given to the mysterious and powerful low frequency signal which began emanating from the Soviet Union in 1976. For more clues to the mystery, the Duga at Chernobyl was the focus of the 2015 documentary film, The Russian Woodpecker, by Chad Gracia. Russian Woodpecker was a high-powered over-the-horizon radar system which used HF (also known as shortwave) frequencies in the 70s/80s. When a second Woodpecker appeared, this one located in eastern Russia but also pointed toward the US and covering blank spots in the first system's pattern, this conclusion became inescapable. The mysterious and unclaimed signal was a source for much speculation, giving rise to theories such as Soviet mind control and weather control. The game heavily features actual locations in the area, including the Duga-3 array. NATO was very confident that the Russian Woodpecker was some kind of over-the-horizon radar system. Confusion due to small differences in the reports being made from various military sources led to the site being alternately located near Kiev, Minsk, Chernobyl, Gomel or Chernihiv. When a second Woodpecker appeared, this one located in eastern Russia but also pointed toward the US and covering blank spots in the first system's pattern, this conclusion became inescapable.
