根据异常回波特征和报警信息判断雷达故障部位

Diagnosing Fault Position of Radar Based on Abnormal Echo Features and Alarm Information

对CINRAD/SA雷达发射机、接收机、伺服系统等不同部位硬件故障产生的异常回波、雷达数据和报警信息进行了分析。指出通过建立实时雷达状态信息库,对基数据进行雷达状态参数检查,形成包含基数据、状态参数、和报警信息在内的异常回波数据块,可实现实时雷达数据质量控制,提高新一代天气雷达数据质量。实际工作中业务人员可通过调用实时数据库获取数据质量信息,对雷达数据是否准确和可用进行判断。根据石家庄雷达站应用统计,可以对90%以上的异常回波数据进行剔除,为故障自动识别和探测技术方法的改善提供参考。

Abnormal echoes because of transmitter, receiver, and servo fault were analyzed in this article. Affection to archive data and the alarm of different fault were analyzed also. The result shows that con- structing radar status information database, inspecting radar status information of archive, and forming abnormal data block including archive, status, and alarm can improve data quality, supply credibility infor- mation for users. According to statistics of Shijiazhuang radar site, 90% abnormal radar data can be elimi- nated. These supply reference for radar data quality control, fault diagnosing, and sounding technology improvement.
