Duga (Russian: Дуга) was a Soviet over-the-horizon (OTH) radar system used as part of the Soviet anti-ballistic missile early-warning network. The system operated from July 1976 to December 1989. Two operational Duga radars were deployed, one near Chernobyl and Chernihiv in the Ukrainian SSR (present-day Ukraine), the other in eastern Siberia.
The Duga systems were extremely powerful, over 10 MW in some cases, and broadcast in the shortwave radio bands. They appeared without warning, sounding like a sharp, repetitive tapping noise at 10 Hz,[1] which led to it being nicknamed by shortwave listeners the Russian Woodpecker. 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. The signal became such a nuisance that some receivers such as amateur radios and televisions actually began including 'Woodpecker Blankers' in their circuit designs in an effort to filter out the interference.
The unclaimed signal was a source for much speculation, giving rise to theories such as Soviet mind control and weather control experiments. However, because of its distinctive transmission pattern, many experts and amateur radio hobbyists quickly realized it to be an over-the-horizon radar system. NATO military intelligence had already given it the reporting name STEEL WORK or STEEL YARD. While the amateur radio community was well aware of the system, this theory was not publicly confirmed until after the fall of the Soviet Union.\
Руфинг на секретный заброшенный советский радар "Дуга",находящийся в чернобыльской зоне отчуждения.Обьект "Чернобыль-2".
«Дуга́» (5Н32) - советская загоризонтная радиолокационная станция для системы раннего обнаружения пусков межконтинентальных баллистических ракет.
Антенны построены по принципу фазированной антенной решётки. Поскольку одна антенна не могла перекрывать такую широкую полосу частот, весь диапазон разбит на два поддиапазона, и антенных решеток поставлено тоже две:
Низкочастотная антенна: высота мачт от 135 до 150 метров, длина - от 300 до 500 метров.[2] На картах Google длина составляет 460 метров.
Высокочастотная антенна: порядка 250 метров в длину и до 100 метров в высоту.[2] На картах длина - 230 метров.
При таких размерах объект виден почти с любого места Чернобыльской зоны отчуждения.[3]
Рядом находилась станция Возвратно-наклонного зондирования ионосферы "Круг", которая предназначалась как вспомогательная к ЗГРЛС а также для выработки текущей информации о прохождении радиоволн, состояния среды их прохождения, выборе оптимального частотного диапазона.
