摘要
卫星系统被未知干扰源干扰的情况日益普遍,来自地面或空中的干扰对卫星系统业务具有严重影响,因此必须对干扰源进行准确监测与定位。对卫星RDSS业务和RNSS业务干扰源监测与定位的有关理论和方案进行了研究,分别对干扰卫星和接收机两种情况,对干扰监测和干扰定位方法和实际工作流程等进行了分析,对于卫星系统的防护具有重要意义。
Interference to satellite systems caused by unknown sources are becoming common today. To eliminate the interferences from the ground and the sky, the detection and location of their sources become critically necessary. This paper focuses on the theories and schemes on the detection and location of the interference sources in satellite RDSS and RNSS. It analyzes the methods and operation procedures of interference detection and location respectively for interferences to satellite and to receiver. The study is of great significance to the protection of sateUite systems.
