Traditional ship identification systems have difficulty in identifying illegal or broken ships, but the wakes generated by ships can be used as a major feature for identification. However, multi-ship and multi-scale wake detection is also big challenge. This paper combines geometric pixel characteristics of their Synthetic Aperture Radar (SAR) images proposes method detection. first detects highlight area image then generates specific windows around centroid, thereby detecting different sizes areas. In addition, all components located completely based on clustering, statistical features axis pixels to determine visible length wake. Test results Gaofen-3 SAR show special potential
