Daryal radar

The Daryal-type radar is a Soviet bistatic phased-array early warning radar. It consists of two separate large phased-array antennas separated by around 500 metres (1,640 ft) to 1.5 kilometres (4,921 ft). The transmitter array is 30x40 m (98x131 ft) and the receiver is 80x80 m (262x252 ft) in size. The system is a VHF system operating at a wavelength of 1.5 to 2 meters (150 to 200 MHz). Its initial transmit capacity was 50 MW with a target capacity of 350 MW.^[1]

Originally, at least seven Daryal facilities were planned, however, only the first two facilities completed, Pechora and Qabala, remained as of 2002.^[2] Two Daryal-U type were to be built at sites in Balkhash and Mishelevka, Irkutsk, neither were completed. The Clinton administration offered financial assistance in completing the Mishelevka facility in exchange for amending the ABM treaty to allow US deployment of a national missile defense system.^[3] Two Daryal-UM systems were to be constructed at in Skrunda, Latvia and Mukachevo, Ukraine. The Mukachevo in the Ukraine was never completed after the fall of the Soviet Union and the Skrunda facility was turned over to Latvia to be demolished, apparently arranged by the US Department of Defence.^[4][2] The Yeniseysk (Krasnoyarsk) Daryal-U site caused concern in the west over compliance with the Anti-Ballistic Missile Treaty during its construction in the 1980s. Following years of negotiations, in September 1989 the Soviets admitted it was a violation of the treaty, construction ceased and the facility was eventually dismantled.^[5]
