This paper describes the concept to design ship detection and identification systemwith combined use of Automatic Identification System (AIS) reports over Synthetic Aperture Radar (SAR) data. TerraSAR-X data (HH-polarization) in spotlight mode acquired on May 2, 2010 is used in this work with AIS-reports taken as ground truth. Till so far, only ship detection algorithms like CFAR (Constant False Alarm Rate), Alpha-stable distribution etc. were presented in most of the literatures for ship detection but also there are some limitation for ship detection performance like metrological conditions, image properties, speckle noise occurrence etc. Here, we present integration concept of both data by means of time matching of AIS-reports with image acquisition in order to estimate ship’s dead-reckoning (DR) location from AIS-report and are projected over an image along with the ship’s hull design for suitability and accurate reliability results. Nearest distance search method are applied to designate the SAR-derived ship targets within certain region of interest around DR. At last, DR based ship’s hull pattern is shifted over SAR-derived ship targets to conclude matched performance result in a well suitable manner.
