英文摘要: This project researches on theoretical model and key methods of target behavior recognition and event mining for high resolution SAR image, and aims at providing new theory and new methods of target behavior recognition and event mining for high resolution SAR image with general use. This project focuses on three scientific problems, which are: 1) research on methods for SAR image target attribute recognition with full consideration of multiple imaging factors. Solve the problem caused by incomprehensive consideration to the multiple imaging factors of image in the current methods to improve the robustness and generalizability for target attribute recognition. 2) Research on methods for SAR image target behavior recognition in a certain time interval. Find the optimum target behavior features and behavior description model which describes the target behaviors according with the actual behavior discriminant rule to correctly decide the target behavior in a certain time interval. 3) Research on methods for mining SAR image target group event, which formed by complex behaviors of multiple targets with mutual correlation. Search the optimum event features and event description model which reflects the dependence and potential correlation of the behaviors of the multiple targets and describes the events according wit
