Abstract: A ship target detection algorithm is developed, which separates land and ocean areas in SAR image firstly and detects the ship targets in ocean subscene separated from SAR image secondly using the moment invariant automatic thresholding method. The results of data processing show that the method is efficient, fast and accurate to detect the ship targets in SAR images.
