EVALUATION METHOD OF RADIO COUNTERMEASURE EFFICIENCY OF SIGNAL OF SATELLITE COMMUNICATION BY INTERFERENCE INFLUENCE ON RECEIVING SYSTEMS OF RETRANSLATORS, AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC G01S13/88 

FIELD: radio engineering.

SUBSTANCE: objective control of radio countermeasure efficiency is provided by availability of two transmission circuits of satellite communication signals and interference: of the first circuit - "ground satellite communication system - SV (space vehicle) - ground satellite communication system" or "ground satellite communication system - SV - system of interference of satellite communication" and the second circuit - "system of interference of satellite communication - SV - system of interference of satellite communication" or "system of interference of satellite communication - SV - ground satellite communication system". In system of interference of satellite communication it is possible to observe in SV-Earth direction the satellite communication signals chosen for suppression at absent interference and cumulative interference and joint signals at impact of interference. At that, in radar surveillance equipment of system of interference of satellite communication there measured is level of power and carrying (central) frequency of received satellite communication signals in SV-Earth direction. As per measured parametres there measured is ratio of powers of interference signal and power of satellite communication signal and mismatch of frequency between satellite communication signal and interference signal, and results of those calculations serve as data for evaluation of efficiency of radio countermeasure.

EFFECT: improving evaluation efficiency of radio countermeasure of satellite communication.
