摘　　要：针对大型米波雷达缺乏快速有效的天线故障检测手段的问题,提出了利用地面反射场法和中场三点法相结合的方式进行天线故障检测的方法,并搭建了试验系统。试验结果表明,该方法能够快速有效地检测并标定出故障天线的位置信息。Aiming at the lack of fast and effective antenna fault detection methods for large-scale meter-wave radars,this paper proposes an antenna fault detection method using the combination of ground reflection field method and midfield three-point method,and builds a test system.The test results show that this method can quickly and effectively detect and calibrate the location information of the faulty antenna.
