| 摘 要： | 针对近年来CINRAD/CC雷达无回波故障现象,对出现在天馈系统、发射系统、接收系统、信号处理系统中的故障原因进行整理和分析,发现各系统故障存在一些不同的特征。结合CINRAD/CC雷达回波信号的接收流程以及各分系统的工作原理,采用分类法和逐级判断法,检查雷达状态参数,给出各系统出现无回波故障的检修方法,并提供一些测试数据、关键点测试波形作为维修参考,实际工作中业务人员可通过这些指标进行故障判断和维修。以普洱站一次无回波故障的检修实例,描述如何根据终端参数和各分系统的监测点参数变化情况,对故障原因进行判断,按照信号流程采用分段法对关键点进行分析和测试,找出故障点并排除,同时对整个故障的排除过程进行总结,供技术人员探讨。

| Abstract: | Based on the facts that there are no echo signals in CINRAD/CC Radar in the past few years, the faults in the antenna subsystem, launch subsystem, receiving subsystem, and signal processing subsystem are sorted and analyzed. It is found that the faults have different properties. According to the receiving flow of radar echo signals and the working principles of each subsystem, by using classification and gradual diagnostic methods, the maintenance methods for faults without echo signals for each subsystem are described through analyzing radar status parameters. Some test data and waveforms of key points are also provided as references for maintenance. Technicians can eliminate faults and maintain equipment based on these indexes in practical work. Taking Puer Station as an example, the procedures to eliminate faults are described according to the terminal parameters and the variation of parameters at monitoring points. Based on the signal flow, the fault was eliminated through the segmental measurement and analysis of key points. The process of the fault elimination is summarized, which is of reference value for the related professionals. |
