摘　　要：根据卫星通信系统的特点,分析了对上下行信号侦收和干扰的可行性。提出了利用空间功率合成技术完成对上行信号的干扰,达到了增强干扰功率的目的,突破了功率器件的制约。进一步分析了天线数量、天线指向精度和多路不平衡度对功率合成的影响。通过仿真验证了算法的可行性和有效性。According to the characteristics of satellite communication system, the feasibility of uplink and downlink signal which are scouted and interfered is analyzed. The spatial power-combination technology is presented to jam uplink signal. The purpose of increasing jamming power is completed and the restriction of power device is broken through. The function between the number of antenna, pointing precision of antenna, multiple imbalance and power-combination technology is further analyzed. The feasibility and effectiveness of algorithm is validated with simulation.
