PROTECTION OF SATELLITE COMMUNICATION SYSTEMS FROM RADIO ELECTRONIC SUPPRESSION

Abstract

The results of analysis of methods of the special satellite lines from the radio electronic suppression are presented in the article. It is considered some perspective directions of antijamming of the satellite communication systems for example of three systems, such as: the system antijamming with spatial indemnification of hindrances; the system antijamming with carrying “receiving” and “transmitter” companions-repeaters (СR); the system monitoring and analysis of radiations of companions-repeaters. The use of spatial indemnification of hindrances allows to reduce their influence on 20…30 dB in a centimeter and decimeter ranges of waves, in the relative (to 50%) stripe of frequencies. Setting about companions-repeaters allows to hide from an opponent position of receiving СR and to prevent influence on him intentional hindrances. The use of automated systems of radio monitoring allows to carry out the analysis of radiations of СR, educe the location of source of hindrances and remove their influence.
