短波、超短波和微波频段等多种无线信道是战术通信的主要传输通道，它是

一种开放式的自然资源，不会被消耗，不使用是浪费；但它具有与其它自然资源

不同的属性，如果使用或设计不当将会造成电波秩序混乱，特别是当多信道传输

设备聚集在一个有限的空间之内时，会引起严重的互干扰。本论文针对战术通信系统中所面临的己方电磁干扰问题，较为深入地研究了

多信道互干扰的产生原因和处理方法。

-Multiple wireless channels such as short wave，ultrashort wave and microwave

ehannel are main signal paths for tactical communication．It is a kind of open natural

resource，which will not be consumed，and will be wasted if not properly utilized．

However,it has different features　other natural resollrces．If not properly designed

or used，chaos in order of electrie wave Can be caused,especially, sever mutual

interference Can occur when multichannel transport devices are put together in a limited space．TIlis paper focuses on the problem of electromagnetic interference confronted in

tactical communication system．It studies the causes and tries to find solutions of

multichannel mutual interference．Briefly speaking，it covers the following issues：
