摘　　要：在雷达链工作中,由于多站雷达信号相互影响,经常引起雷达跟踪目标出现丢失现象,文中对此问题进行了深入分析和计算,给出了雷达移相距离偏短、前卫门宽度与应答机恢复时间不匹配是引起雷达链工作时出现跟踪应答回波丢失的主要原因,并提出了改进方法和解决对策,对提高雷达链中多站雷达的捕获跟踪性能有一定的应用价值。The purpose of this paper is to deal with a problem which is about the target losing because of the interference during the tracking procedure in a multi-radars chain.By analyzing,there are two reasons for this problem.The first is that radar shift phase range is too small,the other is radar responder protecting gate width does not match the responder resuming time.A contermeasure is provided in this paper to solve this problem,which is useful to improve the multi-radars chain ability in capturing and track...
