CINRAD/SA天气雷达伺服系统特殊故障分析

Analysis of CINRAD/SA Weather Radar Servo System Special Malfunction

CINRAD/SA天气雷达投入业务运行以来,在雷达天伺系统出现了较多的特殊故障。从连云港等多个CINRAD/SA雷达中,选取该型号雷达由天伺系统造成PUP图像产品异常的特殊故障,通过使用RDASOT测试程序、测量电机测速反馈电压、分析雷达基数据等方法,分析其故障的成因。

Since the CINRAD/SA weather radars run operationally, many special malfunctions have appeared in the antenna and servo systems. Some special malfunctions of antenna and servo system are selected from some CINRAD/SA weather radars including Lianyungang weather radar, which result in PUP picture abnormity. The causation is detected, by using the RDASOT test program, measuring the feedback voltage of the electromotor which is for measuring the rate, and analyzing the base data of the radar.
