A vessel detection method based on gravity enhancement was applied to Synthetic Aperture Radar (SAR) images. With the method, targets' pixels were enhanced by the interactions between themselves and their neighbors, while the speckle and background clutter were suppressed after enhancement as well as the contrasts between targets and clutter had been greatly increased. Then vessels were detected with the improved K-CFAR detector. East China Sea, off the east coast of Shanghai, China, was chosen as the experiment region. Fine resolution mode and scanSAR mode ALOS PALSAR data were utilized to validate the method. Experiment results show the method proposed in this paper have good ability for vessel detection in SAR image.
