摘　　要：发射机是雷达的关键器件,其输出的射频信号正常与否直接决定了雷达工作的可靠性。为了提升保障人员对某型雷达发射机射频信号异常时的分析排除能力,总结了该型雷达发射机射频信号异常的主要形式,分析了该型雷达发射机的工作机理。在此基础上,构建了该型雷达发射机射频信号异常的故障原因树,根据构建的故障树,进行了该型雷达发射机射频信号异常案例的分析定位排除,为该型雷达发射机射频信号异常时故障的快速定位排除提供了参考意见。The transmitter is a key component of radar,and whether the RF signal it outputs is normal directly determines the reliability of radar operation.In order to improve the ability of support personnel to analyze and exclude the abnormal frequency signal of a radar transmitter,the main forms of the abnormal RF signal of the radar transmitter are summarized,and the working mechanism of the radar transmitter is analyzed.On this basis,the fault cause tree of the RF signal anomaly of the radar transmitter is constructed.According to the fault tree,the case of the RF signal anomaly of the radar transmitter is analyzed,located and eliminated,which provides a reference for the quick location and elimination of the fault when the RF signal of the radar transmitter is abnormal.
