An anti-jamming satellite communication system with high Gp based on OBP de hopping for multi FH as a whole

In accordance with the features of jamming and anti jamming in satellite communications, a scheme of satellite communication system with high anti jamming capacity, which is implemented by onborad signal processing, spreading spectrum technique and other techniques, is presented. Some key techniques are studied and simulated on computers. Usually, this system possesses the lowest anti jamming capacity of 35 dB, with the highest capacity reaching 60 dB or more.
