Abstract
In this paper, a new algorithm for detecting ship and removing azimuth ambiguities is presented. The proposed method is developed by combing the third eigenvalue and the Geometrical Perturbation-Polarimetric Notch Filter (GP-PNF) methods. We firstly improve the GP-PNF feature vector with the third eigenvalue calculated by the eigenvalues-eigenvector decomposition method. Then, the new feature vector is used to remove azimuth ambiguities in the framework of the GP-PNF method. To demonstrate the effectiveness of the proposed method, we exploited one AIRSAR C-band dataset here. In comparing with the traditional GP-PNF method, we find our method has a better capability in removing azimuth ambiguities and detect real ships.
