Duga (Russian: Дуга, lit. 'arc' or 'curve') was an over-the-horizon radar (OTH) system used in the Soviet Union as part of its early-warning radar network for missile defense. It operated from July 1976 to December 1989.

Duga-1 is one of the three Soviet ‘over the horizon’ radar stations. A system made for early detection of attacks by ballistic rockets. This radar system was developed in the Soviet Union in the 1950s, during the Cold War. The array station was hidden in a forest together with the secret military town Chernobyl-2.

Duga远程警戒雷达是苏联在冷战时期所建设的超视距雷达，是苏联反弹道导弹远程警戒网络的一部分，于1976年7月至1989年12月期间服役。 该系统总共部署了两套，一套位于乌克兰苏维埃社会主义共和国（今天的乌克兰）境内的切尔诺贝利与切尔尼戈夫附近，另一套 ...

The Duga-1 radar, nicknamed the Russian Woodpecker, was located near the town of Chernobyl but was abandoned shortly after the disaster.

Duga-1 operated two antennas, receiver and transmitter, 60 km apart from each other. Transmitter was located in military town Liubech-1, Northern Ukraine. The other part of this Duga, antenna which had to receive the signal, was built 10 km away from Chernobyl town. It consisted of two parts to cover wider range of frequencies.

2019年7月25日 · The Duga Radar (Russian: Дуга), nicknamed the "Russian Woodpecker", was a Soviet over-the-horizon (OTH) radar system used as part of the Soviet missile defense early-warning radar network. The system operated from July 1976 to December 1989.

2021年8月12日 · Despite the size, the Soviets built two, one near the now-abandoned town of Chernobyl, which was called DUGA-1, and another in Siberia, called DUGA-2. The radars were protected by their own air-defense systems to ensure their survival during a conflict.

DUGA-1. Even before the successful testing of the experimental station at Nikolayev in 1969 was complete, it was agreed that a larger over-the-horizon radar, DUGA-1, would be built in Chernobyl-2, a settlement close to the (then only planned) nuclear power plant of the same name.

2011年1月3日 · The DUGA-1 site was abandoned in 1989 due in part to significant radiation contamination from the explosion and melt down of the Chernobyl nuclear power plant (and the implosion and melt down of the “Union of Soviet Socialist Republics” and the Communist Party).
