Moving ships produce a set of waves of “V” pattern on the ocean. These wavescan often be seen by Synthetic Aperture Radar (SAR). The detection of these wakes can provideimportant information for surveillance of shipping, such as ship traveling direction and speed.A novel approach to the detection of ship wakes in SAR images based on frequency domainis provided in this letter. Compared with traditional Radon-based approaches, computation isreduced by 20%-40% without losing nearly any of detection performance. The testing results usingreal data and simulation of synthetic SAR images test the algorithm’s feasibility and robustness.
