Research of Radar Transmitter Fault Quick Diagnosis Based on Information Fusion

When the radar transmitter faults are diagnosed using single sensor, the source of fault information is limited, the accuracy and reliability of fault diagnosis are low. In order to solve this question, taking advantage of the transmitter temperature characteristic, a method of fault diagnosis based on multisensor information fusion is presented. The model and algorithm of information fusion are given, and the structure and principle of fault diagnosis system are described. This system has improved the accuracy and reliability of fault diagnosis, raising the efficiency and provides a new way for fault diagnosis.
