Abstract

In the event of emergencies, if satellites transponders are blocked or destroyed, we can transfer the signal to another transponder or satellite without detection of a third party, which is called satellite parasitic communication. This paper put forward a novel satellite parasitic communication system. This system can meet not only communication hidden nature, but also communication reliability. The characteristic of this system is that it takes use of wideband spread spectrum technology and a novel MSAT (Micro Small Aperture Terminal). Firstly, this novel spread spectrum system parasitic performance is analyzed theoretically. The results show that: (1) the larger number of parasitic spread spectrum signals, the greater decrease of signal-to-noise (SNR), (2) the greater SNR of the business channel, the greater decline of SNR caused by the parasitic, (3) when the business channel SNR and the parasitic number of the spread signal are constant, the higher the interference tolerance of the spread spectrum signal, the smaller the reduction of SNR to the original business signals. At last, taking use of Forwarding-satellite test system resources, this novel parasitic satellite communication system performance test on the television broadcast signal is taken. The results show that the MSAT signal and the broadcast television can work together with good parasitic performance.
