Design and Implementation of an Embedded Diagnosis System for Radar Built-in Test Equipment

This paper describes a kind of embedded diagnosis expert system for radar built-in test equipment(BITE). Based on gradation diagnosis model and fault separation tree, diagnosis knowledge is represented by integrated framework, and the direct inference, reverse inference and hybrid inference diagnosis strategy are carried out in radar system. Site test results showed that the diagnosis system could improve fault diagnosis accuracy and speed for modern radar fault diagnosis.
