Analysis of Sea Clutter Distribution and Evaluation of Ship Detection Performance for Sentinel-1 SAR Data

摘要

This paper statistically analyzed the sea clutter distribution and ship detection performance for Sentinel-1 synthetic aperture radar image. First, the goodness-of-fit of five commonly used distribution models were evaluated to find out the most suitable model and the Kullback-Leibler Distance was adopted to judge the fitting degree. Then construct a constant false alarm rate detector for ship detection. To measure the robustness of the detector, the figure of merit, the probability of detection, and the false alarm rate were calculated to evaluate detector performance.
