针对某发射基地首区雷达出现应答机多触发现象,介绍了雷达链的基本工作原理,分析了多触发现象产生时雷达跟踪数据。通过理论分析论证,并结合试验数据以及雷达显示图像,对雷达在应答工作方式下回波信号多次触发现象机理进行了分析研究,并提出技术改进措施。

In allusion to the phenomenon of repetitive trigger of pulse radar in a certain rocketdrome, the basic principle of radar chain is introduced in this paper. At the same time, the radar raw measure data is analysed when the phenomenon of repetitive trigger appears. By theoretic analysis and demonstration, and experimentation data and display image of radar, the mechanism of the repetitive trigger of pulse radar is analysed when radar works with responder beacon. In the end, the resolvent for the problem is brought forward.
