Automatic recombination structure of hollow pipe primary radar apparatus

The utility model discloses an automatic recombination structure of a hollow pipe primary radar apparatus, which is the key technology to ensure the continuous and ceaseless operation of the primary radar. The hollow pipe primary radar technology is complex and the apparatus quantity is large such that in order to ensure the continuous and ceaseless operation of a radar system, two set of redundant system structures are employed. When work channels of the radar system break down, a monitoring branch system can automatically switch redundant backup channels to work channels to ensure the ceaseless operation of the radar system. And meanwhile fault problems of fault channels can be eliminated through on-line maintenance in order to make the fault channels become intact redundant backup channels again. According to the utility model, local apparatuses are recombined to ensure the ceaseless operation of the radar system even the work channels and redundant channels of the radar system break down at the same time.
