中文摘要: 发射机是CINRAD/SA雷达的重要组成部分,由于结构复杂,长期处于连续高压 强电的工作状态,其故障率往往是几个分机系统中最高的,而且发射机系统的故障基本都是 强迫整机瘫痪的“不可工作”级别的恶性故障,严重影响日常的观测业务。基于CINRAD/SA 雷达发射功率一次异常的陡降现象,深入分析其原因,发现高频脉冲形成器的损坏导致脉冲 宽度变小,脉冲信号的占空比也随之减小,从而引起发射功率的下降。同时,对故障源的查 找、定位方法也做了详细的阐述。
Abstract:The transmitter is an important part in CINRAD/SA radar. Because of its comp lex structure and running in the state of uninterrupted high voltage, a highest failure rate occurs among several extensions of radar system. Generally, th e rad ar system will be forced to halt once this fatal failure occurred. Based on an a b normal CINRAD/SA radar transmitter power decline, we find out that the failure lie s in the high frequency pulse generator, which makes the pulse width depressed. And also, some maintenance methods are summed up here, from which the rad ar maintenance professional could take as reference.
