Abstract:

Analysis and simulation of spectrum surveillance effectiveness for GEO region are carried out in this paper. Firstly, the analysis of target coverage probability and surveillance probability is implemented based on the main-lobe of target satellite antenna. The results show the invalidity of this method. Secondly, the method of spectrum surveillance based on the side-lobe of target satellite antenna is proposed. The theoretic analysis demonstrates that it can cover all GEO target satellites if meeting the constraint relation among orbit altitude difference, surveillance angle and surveillance range. Lastly, taking all on-orbit GEO satellites as target samples, the simulation and analysis of target coverage probability are implemented. The results show that this method for spectrum surveillance of GEO region based on the side-lobe of target satellite antenna is feasible.
