摘　　要：本文分析CINRAD/SA雷达伺服系统运行不稳定,主要有雷达方位俯仰定位超限、跳变、伺服故障等原因,造成雷达回波异常,并将回波异常分为3类。研究从雷达基数据中检测出雷达伺服系统方位俯仰的定位超限、跳变、故障等质控判别方法,及时发现雷达存在的异常回波问题,推送预警短信,指导台站及时进行维护维修,从而在源头上控制由于雷达伺服系统原因造成的异常回波资料生成,提升雷达数据和产品质量。The unstable operation of the CINRAD/SA radar servo system is analyzed,and abnormal radar echoes,which are mainly caused by servo faults,the overrunning and jumping of positioning of radar azimuth pitch,are divided into three categories.We study the quality control method of the overrunning,jumping,and faults of azimuth pitch positioning of the radar servo system from the radar base data,which can timely detect the abnormal echoes problems of radar,release the warning message,guide the maintenance in time,control the generation of abnormal echo data induced by the radar servo system from the sources,and improve the radar data and product quality.
