摘　　要：介绍了相控阵雷达T/R组件在设计和使用过程中遇到的一些电磁兼容问题,从原理上进行了初步分析:一是T/R组件腔体内的空间耦合影响,包括各功能模块电路之间的相互影响,如发射通道和接收通道之间、微波电路和波控电路之间,通道之间的相互耦合;二是收发转换时的时序影响;三是发射脉冲时的前后沿抖动影响;并提出了相应的解决方法。The first aspect is effect of space coupling in T/R module chamber, involved with mutual effect between function module circuits, such as mutual couplings between transmitting channels and receiving channels, between beam-steering circuits and microwave circuits, between channels. Second one is sequence influences at the time of converting between transmitting and receiving. The third is influence of pulse edges jitter at the time of pulse transmitting.
