卫星通信系统在上、下行综合干扰条件下的性能分析

Analysis on Performance of satcom system with Integrated Jamming of Up-links and Down-links

研究了卫星转发器分别工作于线性状态和限幅状态时,同时存在的上行干扰和下行干扰对整个通信链路的载波与噪声干扰比的影响,并以某一卫星通信系统为例进行了具体分析,验证了采用上行干扰和下行干扰进行综合对抗时,将会取得更好的干扰效果,为干扰卫星通信采用新方法提供了一定的理论依据。

The effect of coexistent jamming of up-links and down-links to the ratio--the power of carrier wave to that of noise and jamming of the whole communication course-is studied when the transponder of satellite works in the conditions of linearity and saturation, respectively. Then a satcom system is analyzed concretely as an example for validating that it would obtain better interference purpose when adopting the integrated jamming of up-links and down-links. It provides theoretic basis for jamming satcom adopting new methods.
