摘　　要：2009年2月8日至16日徐州天气雷达开机过程中,产品出现断断续续的拉丝现象,产品拉丝处图像掩盖了实际回波,而检查雷达的各项标校参数,其值均在正常范围且无任何报警,雷达回波异常,使雷达不能正常发挥其有效的作用。通过对CINRAD/A雷达伺服信号链路进行分析,查找闪码故障的产生原因和检测检修方法,为雷达技术保障人员提供现场维修、维护方面的经验。In the period of CINRAD/SA radar location updating during 8--16 February 2009, wiredrawing phenomena were discovered in the radar products from time to time. Real images were overspread by the positions of wiredrawing. There are no alarms or abnormality by checking radar parameter criteria. We cannot use those abnormal images if the radar could not work regularly. By analyzing the servo signals of radar, we have found the causes for the malfunction and the method of maintenance.
