Dunay radar (Шаблон:Lang-rus literally Danube; NATO: Cat House, Dog House) was a system of two Soviet radars used to detect American ballistic missiles fired at Moscow. They were part of the A-35 anti-ballistic missile system.[1] One sector of one of the radars, the Dunay-3U ("Cat House") is still operational and is run by the Russian Space Forces as part of the Main Control Centre of Outer Space.[2]
Dunay-2
The Dunay-2 was a prototype built in Sary Shagan as part of the experimental missile defence system "A". It consisted of separate transmitter and receiver complexes separated by Шаблон:Convert. The power of the radar was 100 kW and its range was Шаблон:Convert.[3][4] The NATO codename was "Hen Roost".
Dunay-3M
The Dunay-3 (Шаблон:Lang-rus; NATO: Dog House) was an upgrade of the Dunay-2 located in Kubinka, Moscow and became operational in 1968. Following an extensive upgrade in 1978 it was renamed Dunay-3M as part of the upgraded A-35M ABM system. It consisted of separate receiver and transmitter buildings separated by Шаблон:Convert.
The transmitter covered two sectors (roughly north and south) and its array was Шаблон:Convert long and Шаблон:Convert high. The power of each sector was about Шаблон:Val. The receiver was a building Шаблон:Val×Шаблон:Val containing 2 passive electronically scanned array radars as well as the command and control centre for the A-35 system. The range of the system was Шаблон:Convert.
The radar was functional until it caught fire on 8 May 1988.
Dunay-3UP
This was a prototype of the Dunay-3U and was located in Sary Shagan test site.[2] It was given the NATO codename "Top Roost".
Dunay-3U
The Dunay-3U (Шаблон:Lang-rus; NATO: Cat House) was built in 1978 as part of the upgraded A-35M anti-ballistic missile system. It is located in Chekhov and was structurally similar to the Dunay-3M – it has a separate receiver and transmitter separated by Шаблон:Convert. There are two sectors. It was capable of identifying the launch of Pershing II missiles from West Germany.[5]
In 1995 A-35M was replaced by the A-135 anti-ballistic missile system which used the Don-2N radar. One sector was decommissioned in 1998 and is now ruined and the other is used for space surveillance of satellites in low Earth orbit. As a UHF radar it can identify smaller objects (15–40 cm) than the VHF radars such as the Daryal and Dnepr.[2]
The Dunay-3U was commissioned in May 1978 with a life of 12 years. Both sectors were extended until 2000 but one sector (62) was decommissioned in 1998. The other one (61) has been extended in 2001 and 2005 – the last extension was until December 2009,[2] but it may have been extended again. In 2012 the Russian Ministry of Defence issued a tender for the demolition of sector 62.[6]
Before 2003 the transmitter had 30 waveguides each excited by a Шаблон:Val transmitter. Since 2003 the station has been operating at a reduced power of Шаблон:Val rather than Шаблон:Val, with 12 transmitters (out of 24) rather than the previous maximum of 30. The radar is chirped.[2]
The radar's computer system is made up of 10 K340 computers.[2]
