An Algorithm of Searching the Best Receiving Point through the Side-Lobe of the Synchronous Communication Satellite

Determining how to search for the best receiving point of the satellite ground receiving station is the main objective, when it can only be set in the area where the side lobe of the transmitting antenna in the synchronous satellite covers. The scenario of the synchronous satellite communication system was built with the help of the STK software, the method of building the antenna model was introduced. Based on the scenario, by bringing in the GA, the algorithm of how to search the best receiving point rapidly and accurately was given. The comparison of the simulation results shows that the algorithm of this paper gives a better performance on the time costing and calculation speed than the conventional method, so the algorithm given by this paper has some application value.
