1C12 target detection station

Станция обнаружения целей 1С12

The 1C12 target detection station - a rangefinder radar of the centimeter range (2.2-2.3 GHz) was used for target reconnaissance. In combination with one - two radio altimeters PRV-9A the same station under the name P-40 ("Armor") was used in the radar companies of the military air defense.

The radar was developed by NII-208 (later the Research Institute of the Ministry of Radio Industry) under the guidance of Chief Designer V.V.Reisberg.

The 1C12 target detection station provided detection of the fighter at ranges up to 180 km (with a flight height of 12000m) and 70 km for a target flying at an altitude of 500m. Pulse power of radiation of the station was 1.7-1.8 MW, the sensitivity of the receiver was 4.3-7.7E-14 W. During the circular survey 4 beams in the angular plane were successively formed: two lower widths of 2° and 4°, and two upper widths of 10° and 14° . Switching of the beam direction was carried out electromechanically.

The 1C12 station was located on the tracked chassis of the heavy artillery tractor AT-T ("object 426") designed by the Design Bureau of the Kharkov Locomotive Engineering Plant named after A. S. Pushkin. It was designed by the Kharkiv Malyshev Transport Engineering Plant (in combat and marching positions). In terms of a number of indicators, including safety, it was inferior to the chassis based on SU-100P. In this case, the choice of chassis was determined by the weight of the station 1C12, twice as large as the guidance station for missiles.
