CINRAD/SA雷达接收机主通道故障分析及排除

Analysis and troubleshooting of CINRAD/the SA radar receiver lord channel faults

CINRAD/SA(以下简称"SA")雷达接收机是雷达的主要部件,接收机通道故障将造成雷达系统标定数据异常,雷达终端产品无回波。由于接收机主要部件无自动故障定位功能,要确定故障的具体部位,技术人员仅从雷达系统的相关告警信息和提示是无法判断故障的具体所在的。排查工作首先是检测接收机的主通道和测试通道,判断是哪个通道的故障,故障检测主要通过程序标定和仪表检测来进行,分步检查找到故障点,将故障排除。

Receiver is the main parts of radar in CINRAD/SA（call SA as follows）.The fault of the receiver channel will cause the radar system calibration data exception,and the radar terminal product has no radar echo.Main receiver parts have no automatically break down to position function.Technical personnel could not judge breakdown from related warning information and hint of radar screen of the concrete parts.The first checking work is the main passage and test passage that examined a receiver,determining which channel is fault.And the fault detection method is mainly used in the process of calibration and instrument detection to determine the fault point step by step check to find the point of failure and troubleshooting.
