Abstract: Polarimetric SAR images include plenty of scattering mechanism information of targets,which are of important potential in edge detection.In this review,edge detection for polarimetric SAR images is studied systematically,the issues are analyzed which are in edge detection of SAR images along with single polarized images,the existing detectors are classified,the newest progress in polarimetric SAR edge detection is introduced and problems are pointed.In the end,conclusions are made and the possible future work is explained.
