A Support Vector Machine (SVM) based method for ship detection in Polarimetric SAR (POLSAR)
is proposed in this study. Because of similarities of ship and man-made structures on land in scattering
mechanisms, land and sea are first segmented by SVM according to polarimetric features and texture features;
The SVM-based Recursive Feature Elimination (RFE-SVM) approach is adopted to improve the performance
of the segmentation algorithm. Then ship targets are extracted from sea by SVM classifier; Threshold-based
rules and SVM-based rules are established for discriminating ship from non-ship target at last. The experiments
are carried out on POLSAR data from Radarsat-2. For the available SAR images, the average accuracy of ship
detection is over 95%.
Key words: Polarimetric SAR, polarimetric decomposition, ship detection, support vector machine, texture, ,
