Multi-beam satellite communication system
专利汇可以提供Multi-beam satellite communication system专利检索，专利查询，专利分析的服务。并且PURPOSE:To eliminate the consideration to the combination of inter-beam connections, by making the communication signal sent from an earth station at the receiving side, always receivable state then scanning the multi-beam of the transmitting side in response to the demand of communication. CONSTITUTION:The communication information transmitted from an earth station is received at an antenna 11 and then demodulated the base band signal via a receiving amplifier 12, a frequency converter 13 and a demodulator 14. The demodulated communication information is sorted for each communication destination and furthermore converted into transmitting signals through a modulator 6, a frequency converter 17 and a transmitting amplifier 18. These transmitting signals are sent to an RF band switch matrix 19. The matrix 19 allots the scanning spot beam to each communication destination and transmits the communication information to the earth station through a transmitting multi- beam antenna 20. A base band and an RF band switch controller 21 control the sorting the communication information for each destination as well as the allotment of the scanning spot beam.，下面是Multi-beam satellite communication system专利的具体信息内容。
