摘要
工作频率相同的雷达同时工作时会相互干扰,因此需要研究干扰强度,对雷达受到干扰的程度做出判断。目前常用的判断方法没有考虑电磁波多路径的影响,准确度不高。文章分析了多路径效应下的雷达互扰方程,并与未考虑电磁波多路径影响的雷达互扰方程的结果做比较。从仿真结果可以看出,多路径效应对雷达互扰影响较大,特别是当干扰信号水平极化时。
Radars with same frequency interfere each other when they nm at the same time. The intensity of interference need to be studied in order to estimate what extent radars are affected to. The radar interference equation which is used usually is not accurate because of not considering multipath effect. In thispaper, a new radar interference equation modified by multipath is analyzed, and compared with the radar interference equation without multipath. The simulation shows that multipath effect influence radars interference greatly, especially to horizontal polarized electromagnetic waves.
