跳扩频卫星通信干扰效果分析*

摘要

论文介绍了跳扩频卫星通信系统信号级工作流程，对卫星通信干扰方式和卫星通信干扰的入手点进行了叙述，选择了具有代表性的干扰方式对其上行链路进行了通信干扰仿真；在进行了干扰效果评估等级的划分后，依据误码率指标对通信干扰效果进行了定量计算，通过干扰效果分析，得出了梳状谱干扰效果最理想的结论，可为卫星通信干扰方面的研究提供一定的参考。%Based on introducing the signal flow of work of DS/FH satellite communication system ,the paper presents the method of satellite communication jamming and breakthrough point of satellite communication jamming ,and then makes the simulation of up chain communication by choosing representative methods of jamming .After dividing the jamming effect evaluation grade ,the jamming effectiveness is calculated based on the bit error rate and the jamming effectiveness is calculat‐ed to get some meaningful conclusions :comb spectrum jamming is good at jamming theDS/FH satellite communication which can provide some reference for satellite communication jamming .
