Radar purpose and system combined reasoning method based on grey correlation level confidence

The invention discloses a radar purpose and system joint inference method based on grey correlation hierarchy confidence, which comprises the following steps of: firstly, constructing a radar knowledge base containing various known radar signal parameters, then calculating grey correlation similarity between an unknown radar signal to be measured and each record in the radar knowledge base by utilizing a grey correlation analysis method, and calculating the grey correlation similarity between the unknown radar signal to be measured and each record in the radar knowledge base; the method comprises the following steps: firstly, designing similarity, then fusing the similarity through a D-S evidence theory to obtain an accurate classification result of radar purposes, then designing a hierarchical confidence inference engine to accurately judge a radar system, and finally realizing efficient and accurate joint inference of the radar purposes and the radar system. According to the method, the problems that radar
