摘　　要：研究了有干扰时透明转发器卫星通信系统中的互调分量。首先,对有干扰时硬限幅条件下窄带系统的互调分量和 DS 扩频通信系统中的相关互调分量进行了理论分析;然后,针对实际系统,建立了系统仿真模型,进行了计算机性能仿真,通过对仿真结果的分析,得到一些结论。研究成果对了解透明转发器卫星通信系统在强干扰条件下存在的互调分量的影响及其量化结果,从而设计具有针对性的卫星通信抗干扰系统具有实际意义。It is studied that intermodulation products of transparent transponder satcom system with interference. Firstly the theory analysis is done for intermodulation product of narrow band system and coherent intermodulation products of DS spectrum spreading with interference. Then the simulation model is built for the practical system. Some conclusions are given by the simulation results. The research has practical significance for understanding the effect of intermodulation product and its quantization index of transparent transponder satcom system with interference. Thus the corresponding antijamming satcom system is designed.
