Using fault tree analysis to analyze disputes in the new generation weather radar

There are many difficulties in the daily maintenance and support process of the new generation weather radar. A fault tree analysis method is proposed, which combines the working principle of weather radar to construct a fault tree for the new generation weather radar and designs qualitative and quantitative analysis methods to further achieve fault diagnosis. According to this method, the probability and importance of failure occurrence are obtained, and based on specific examples, the probability of system failure P(T)=0.65 is calculated when the probability of underlying events occurring is 5%. This study indicates that radar fault diagnosis algorithms based on fault trees can effectively improve the quality of radar support, thereby pushing the highest probability of faulty component maintenance based on fault codes, and improving fault diagnosis efficiency.
