The principles of the CINRAD/CC radar receiving system are analyzed, and the parameter list of the key points of the CINRAD/CC radar receiving system is given. The common failure analysis methods of radar receiving system are introduced. Eight categories of typical failures and the solution to problems in the receiving system are summarized based on the analysis of receiving system failure phenomena and causes. With the increasing using time of radar equipment, the failure rate increases. Radar repair is complicated and expensive; therefore, the summary and classification of radar failures and the solution to the problem corresponding to the same type of failure are necessary, which can greatly improve radar maintenance efficiency.
