Abstract
The moving vessels exhibit defocusing and other characteristics in SAR images, which brings great challenges to the target detection in the later stage. Combining spaceborne SAR images and AIS information to perform imaging correction analysis of moving vessels is the basis for efficient and accurate detection and identification of moving targets. Firstly, the performance of the moving target in SAR image is analyzed theoretically, and the correctness of the theoretical model is verified by simulation experiments. Then simulation and correlation analysis of the scene with moving target is conducted, with the combination of AIS information. In the case of a status with multi-vessel and multi-motion, the AIS information is introduced together with the SAR results to correct the moving targets and label missed vessels in the image. The results show that with the combination of AIS information and SAR image, it is able to obtain the relative focused position of the moving vessels without offset according to the motion state of the target, as well as efficiently screen the hidden vessels in the AIS.
