SHIP DETECTION FROM POLSAR IMAGERY BASED ON THE SCATTERING DIFFERENCE PARAMETER

In this paper, a new scattering difference parameter named as SDP is first constructed to characterize the relationship between polarimetric covariance matrix [C] and complete polarimetric covariance difference matrix [CP]. Then, by integrating "1-SDP" and the power maximization synthesis detector (PMS) derived from [CP], a novel ship detection method OmSP(cp) is further developed. In order to demonstrate the performance of the proposed method, one AIRSAR L-Band Polarimetric SAR dataset with 22 ships is exploited. The experimental results show that, compared to other methods, OmSP(cp) can hold a better ship detection accuracy.
