摘　　要：文章介绍了CINRAD/SA雷达接收机测试通道的组成,并分别对测试通道各主要部件故障判断方法进行了介绍,同时提出了当出现标定数据异常和系统软件报警且无法对故障进行精确定位的情况下,优先检查测试通道,利用雷达系统软件配合机外仪表,通过测量微波器件各通道的增益或衰减量进行故障定位的方法,为雷达业务保障人员快速排除雷达故障提供了参考。This paper introduces the composition of CINRAD/SA radar receiver test channel,and introduces the fault judgment methods of each main component of the test channel.At the same time,when abnormal calibration data and system software alarm occur and the fault cannot be accurately located,the test channel should be checked first.The radar system software should be used to cooperate with the external instrument to locate the fault by measuring the gain or attenuation of each channel of the microwave device,which provides a reference for radar business support personnel to quickly eliminate radar faults.
