摘要
为全面地总结CTL-713C型天气雷达接收机硬件维护技术,对接收机主要组成电路及作用进行了分析,总结得出接收机整体工作信号流程示意图。由此提出CTL-713C型天气雷达接收机故障分析和检修方法:快速诊断法及通过对射频、中频、视频关键点分类测试进行检修的方法,通过3类故障的检修过程对接收机故障检修方法和流程进行了实际分析和检验,并指出雷达接收机维护检修的原则:通过整体看局部,先易后难,综合测试,熟悉原理。
To summarize the maintenance techniques of the CTL-713C weather radar receiver comprehensively, an analysis is made of the main component circuits and functions of the receiver, and the schematic signal flow chart is presented. The CTL-713C weather radar receiver faults are analyzed, and troubleshooting methods is discussed. The frame of reference for radar receiver maintenance is given： looking through the whole, starting with the easy, testing comprehensively, and being familiar with the working principles.
