COMPARATIVE EVALUATION OF DETECTION PERFORMANCES OF RADAR "COBALT - RLS" WITH FOREIGN RADIO LOCATION STATIONS (RLS) INTENDED FOR MONITORING THE MAN-CAUSED CONTAMINATION OF NEAR-EARTH SPACE

The use of ground radar-tracking facilities for space observations and monitoring the man-caused contamination of near-earth deep space is considered. Brief information about RLS "Haystack" (USA) and "FGAN" (Germany) and a comparison of their performances with the parameters of "Cobalt" RLS (radar) on the basis of the radio telescope THA-1500 are presented. The comparison is carried out onthe criterion of the minimum size of the discovered objects at fixed distances. As a threshold of detection the magnitude of the relative signal / noise equal to 10 dB is accepted.
