Abstract 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.
