摘　　要：2012-03-05T03:53韶关CINRAD/SA天气雷达系统出现噪声温度报警,CW标定和RFD标定偏差值越来越大,SYSCAL值增大,报线性通道增益标定常数异常。经过对故障的逐级分析,找出了故障所在为二位开关联接松动,并得以及时解决。A noise temperature alarm of Shaoguan CINRAD/SA weather radar occurred at 2012-03- 05T03.53. When the deviation values of the CW and RFD calibration increase, the SYSCAL value also increases and linear channel gain calibration constant appears abnormal. According to analyze the faults by steps, the reason that caused the faults is the loose connection of two state switch. Then, its solutions are put forward in time.
