Abstract In this paper, a new algorithm for ship detection with Synthetic Aperture Radar (SAR) images is presented. We develop the proposed method by combing Principal Component Analysis (PCA) and the Geometrical Perturbation-Polarimetric Notch Filter (GP-PNF) method. In the first step, we replace the feature vector composed by the elements of the covariance matrix with more polarimetric features. Then, PCA is used to reduce the feature space. The new reduced feature vector is then used to detect ships by using the framework of the GP-PNF. In order to demonstrate the effectiveness of the proposed method, we exploited Sentinel-1 datasets. In this abstract, a dataset obtained in Gibraltar is considered. A comparison with other methods showed improvements in detection capability.
