A Review of Shadow-based Video SAR Moving Target Detection and Tracking Methods
Video SAR is an advanced radar imaging system that integrates SAR and video imaging technologies.It not only has the characteristics of traditional SAR imaging,but also can acquire rich dynamic information of the target in real time,which has obvi-ous advantages in moving target detection and tracking.The moving target shows obvious shadow feature in the video SAR se-quences,and the shadow feature can approximately reflect the real position of the target.It has the advantages of high positioning accuracy and high detection probability,which makes the moving target detection and tracking technology based on shadow become one of the current research hotspots in the field of video SAR.This paper summarizes the current shadow-based video SAR moving target detection and tracking methods,compares the performance of various methods,analyzes the advantages and shortcomings of current video SAR moving target detection and tracking methods,and clanifies the urgent problems in video SAR moving target de-tection and tracking.
