摘要
新一代天气雷达CINRAD/CD发射机调制系统故障,会直接影响雷达信号的发射,导致雷达无法进行天气探测工作。通过对都匀新一代天气雷达CINRAD/CD在运行过程中发射机调制系统的常见故障,列举2个典型例子,从故障现象着手分析,结合实际工作经验,针对调制系统的组成和工作原理,逐级判断、检查,测试关键电路信号,找出引起故障的根本原因,更准确的实现故障的定位,并给出相应的处理方法。
The failure in a transmitter of the new generation weather radar CINRAD/CD modulation system can affect the radar signals and even result in complete breakdown of the radar system. Two typical faults in the transmitter of the new generation weather radar CINRAD/cD modulation system are described, and the symptoms are analyzed in combination with the practical experiences, through step by step judging, checking, and testing the key circuit signals according to the composition and working principles of the modulation system, to identify the basic causes of failure and locate quickly the failure and then take corresponding countermeasures.
