Abstract Taking a fault of echo weaken of Chengdu new generation weather radar (CINRAD/SC) as the example,this paper introduces the procedures how to analyze and troubleshoot the typical faults in detail.From the failure phenomenon of echo weakened,the parameter configuration,receiving channel and transmitting system of RVP7 signal processor in the terminal processing software are gradually checked.The fault of high power supply in transmitting system is finally found out,which leads to the decreasing of radar transmitted power and echoes weaken.Then,some guides about radar repair and maintenance from this process of failure analysis and removing are summarized.
