Study on Fault Diagnosis for radar´s transmitter based on Bayesian network

Fault Diagnosis for radar´s transmitter is very crucial, yet very difficult. Transmitter is complex electrical equipment whose units are full of uncertain factors and information. The paper puts forward a new fault diagnosis method based on Bayesian network for the transmitter. The cause-result graph of transmitter is gained by analyzing its structure firstly, and then the fault model based on Bayesian network is built. The next step is to study its parameters by using certain algorithm. Finally the fault model is tested, and the experiment results show that the proposed method is very effective for diagnose the faults of transmitter.
