Research on intelligent monitoring and diagnosis system for radar bit

The radar built-in test technique is an important way to improve radar testability, maintainability and diagnostic capability. Recently it´s becoming more valuable and being studied and applied to many areas. An intelligent built-in test system of radar is put forward which can carry out the functions of condition monitoring and fault diagnosis. In this paper, we did a simple introduction about the system´s request, function and structure firstly, and then emphasized on an approach about intelligent diagnosis based on one-class support vector machine. This approach was applied to monitor and diagnose radar fault, and a diagnostic model was built up. It is verified by experiments that the model can carry on effective monitoring and diagnosis to radar fault, and it can also bring out a higher fault detection rate and a lower false alarm rate.
