提空间定位误差造成虚假回波，直接影响雷达观测资料的可靠性，对预报造成干扰。项目小组从全国各 CINRAD／SA台站采集到17个空间定位故障案例，结合 CINRAD／SA 雷达天伺系统电信号流程和关键点的参数特征，对可能导致雷达空间定位误差的所有环节逐个进行分析，归纳总结出 CINRAD／SA 雷达空间定位误差诊断方法。最后从案例库中选取3个典型个例展开分析，对台站快速排除空间定位故障提供指导思路。

Spatial positioning error causes false echoes and affects the reliability of radar observation data, resulting in interference on forecasts directly.Our project team acquired 17 cases from the nationwide CIN-RAD/SA radar stations.Combining with flow direction of antenna servo system signal and parameter char-acteristics of key components,this paper gradually analyzes the factors conducing spatial positioning error and summarizes the method of diagnosing such problems.Finally,three representative cases are analyzed, which provides guidance for removing such malfunction quickly.
