MR-320 “Topaz” (Cyrillic: МР-320 «Топаз-2», NATO designator: “Strut Pair”) is operating in the S-Band air surveillance and acquisition radar. It is designed to detect air, surface and coastal targets, as well as to assign target indication to artillery and anti-aircraft missile weapons. The detection range of a surface target is up to 40 km.
The antenna post is mounted at the top of the fore mast. There are practically two antennas MR-302 “Strut Curve”, which were mounted back-to-back. Each of the antennas covers a different elevation angle, so that a rough height determination is possible.
The radar was added to the armament of the Soviet Navy in 1976. The modernization MR-320 “Topaz-2” also allows passive target tracking of active jammers.
