CINRAD/CD天气雷达天线控制故障的分析与排除

摘要

新一代全相参多普勒天气雷达系统,是集电子、通信、计算机和网络于一体的气象观测设备。雷达天线的操控主要是由伺服系统来完成,在雷达使用过程中出现天线控制异常,多是因为伺服系统出现故障引起,而伺服系统的故障是多种多样的,许多问题导致的最终现象就是天线控制异常。文章例举了几个具有代表性的例子,并对其进行分析,寻找故障根源,提出了相应的故障排除方法及日常维护要点。%A new generation of Doppler weather radar system is the meteorological observation equipment with the integration of electronics, communication, computer and network. Radar antenna is mainly controlled by servo system. In the process of radar operation, abnormality of antenna control is mostly caused by the faults of servo system. Because servo system faults are various, that many problems lead to the ultimate phenomenon is the abnormality of antenna control. This paper enumerates and analyses several representative examples in order to find out fault origins and puts forward the corresponding troubleshooting methods and main points of maintenance.
