SAR IMAGE PROCESSING FOR SHIP WAKE DETECTION
Chavdar Alexandrov, Nikolai Kolev, Miroslav Tsvetkov, Yordan Sivkov In this paper some methods for image processing of Synthetic Apperture Radar images (SAR images) and some algorithms for automatic detection of different objects on the sea surface, including ships and oil spills, are described. Results are demonstrated based on the processing of SAR images, provided by Sentinel 1 A/B satellites of European Space Agency ESA, as well as on using algorithms for automatic detection with constant false alarm rate (CFAR Detection). Some problems are shown related to detection of small non-metal vessels with sizes, comparable with SAR image resolution, i.e. rubber, wooden or small plastic motor boats and possibilities to use their wakes on the sea surface in some specific weather conditions for detection of these vessels. Some possibilities to use results achieved in SAR image processing and object detection for solving these problems are proposed.
