摘　　要：本文对卫星通信的上、下行链路和转发器实施干扰的可行性进行了分析,并详细分析了上行干扰对透明转发器的影响。研究结果表明,对上、下行链路实施干扰的有效途径为升空平台(无人机或卫星)载有干扰设备;对透明转发器卫星通信系统,干扰的有效功率必须大于所有用户的总功率,宽带干扰或梳状谱干扰是较好的干扰方式。This paper analyzes the jamming feasibility to the up/down link and the transponder of satellite communications with emphasis on an analysis of the effect of the uplink jammer on the transparent transponder. Research results show that the effective approach to jamming the up/down link is the blastoff plane (unmanned airplane or satellite) loaded with the jammer machine. For satellite communications system with a transparent transponder, the effective jammer power must be larger than the total power of all the users, where the broadband jammer or comb-spectrum jammer is more satisfying.
