| 摘 要： | 结合CINRAD/SA雷达天线的动态控制过程、结构特点与故障现象,从理论上清晰地分析了天线运行的基本过程,指出各CINRAD站经常、普遍出现的天线座动态故障的实质是雷达天线运行的实际动态速率和位置与RDA(Radar Data Acquisition)计算机给定雷达伺服控制系统的命令不匹配以及判断造成此类故障报警的雷达天线动态速率不匹配条件和位置不匹配条件,而后深入分析了雷达天线伺服控制结构中的D/A转换电路、速度比较电路等关键部件的工作状态,最后总结了排查此类故障的驱动链路检查、滑环维护方法、伺服电机检测方法等,从而为CINRAD/SA雷达天线故障的现场维护和维修提供参考。

| Abstract: | Combined with the CINRAD/SA radar antenna dynamic control process, structural characteristics, and symptoms, the basic processes of antenna operation are analyzed theoretically, and it is pointed out that the main reasons for radar pedestal dynamic faults occurred often in CINRAD stations are the mismatch of the actual position and dynamic rate of the antenna runs and the commands given by the RDA (Radar Data Acquisition) computer to the radar servo control system, and the mismatch of conditions and locations of the radar antenna. An in depth analysis is conducted on the working status of the key components such as the D/A converter circuit and speed compatible circuit, and the troubleshooting is conducted by means of such methods as drive chain, slip ring maintenance, and servo motor check, so as to provide references for the on site maintenance of CINRAD/SA radar antenna failure. |
