Baklan (radar)

from Wikipedia, the free encyclopedia

MR-102 Baklan ( Russian Баклан , German: Kormoran ) is a Soviet surveillance and target tracking radar system, which was mainly used on torpedo and patrol boats. The NATO code name is Pot Drum .

Structure and use

Cuban Turya class boat with Baklan radome on the mast

The system's antenna is located in a flat, slightly curved radome about 1.5 m in diameter. This form is the origin of the NATO code name. The viewing device is a cathode ray tube about 15 cm in diameter. The main task of the system is maritime surveillance and torpedo fire control equipment. In addition, it has limited airspace surveillance capabilities.

The system was used from 1958 and replaced radar devices of the Sarniza (Skin Head) type . At the same time as the MR-102, a very similar radar system, Reja (Pot Head), was developed. This differed in a shorter transmission time, which was an advantage when detecting submarine periscopes. Both systems were replaced on newer boats (from 1978) by the radar Reid (Peel Cone).

The MR-102 system was used in the following ship classes, among others:
