一次CINRAD/CC雷达接收机频率源故障诊断

摘要

The main signal flow of the frequency source for CINRAD/CC radar produced in the 7th batch is described. Through analyzing the main signal flow of the frequency source and using the waveform of the spectrum analyzer on key points, the fault phenomenon and the solution of the frequency source are discussed. The process is expounded, taking a typical fault phenonmenon for example. Requirements for the CC radar frequency source at the center frequency of key points and spectral amplitude are summed up. Some useful hints are given for radar users and the maintenance staff.%简要介绍了第7批次生产的CINRAD/CC雷达频率源分机的主要信号流程,通过分析频率源分机主要信号流程并结合频谱仪对故障各关键点的检测波形,归纳了频率源分机故障现象和排除方法,并以频率源分机的一次典型故障为例对排除过程进行了细致阐述.归纳了CINRAD/CC雷达频率源对关键测试点的中心频率及功率谱幅值要求,提出了雷达技术保障人员基本的技术要求和维修操作中的注意事项,希望对相关雷达站有借鉴作用.
