摘要: 卫星扩频信号的抗干扰性能关系到卫星链路系统的安全性。在高精度测距和有限星载处理能力约束下增加抗干扰环节会增加信号接收机复杂度并且引入测距误差,定量分析扩频测距中的天然抗窄带干扰能力可以为在什么条件下不需要采取抗干扰措施提供决策,对优化系统设计具有重要意义。本文对扩频测距的抗窄带干扰性能限进行了定量计算、分析,设计了实验测试方法和系统,达到了预期目的。

Abstract: The anti jamming performance of transceiver relations security of inter-satellite links system, under high precision ranging and limited spaceborne processing capacity, increasing anti-interference part will increase the complexity of the transceiver and the introducing ranging error, so quantitative analysing natural ability against narrowband interference of spread spectrum ranging can provide decision to not need to take anti-jamming measures, under what conditions. It is important for optimizing system design. The paper takes the performance bound of against interference of inter satellite link transceiver as the research target. Researching on the key technical issues by quantitative calculation, analysis, design experiment test method and system, achieved the desired purpose.
Key words: Inter-satellite links, Antijamming, Narrowband, Performance
