Abstract:

For target detection based on the polarimetric synthetic aperture radar(PolSAR), a distinction parameter between areas of targets and clutters is proposed. The parameter describes the uniformity of a set composed of pixels from areas of targets and clutters, so as to reflect the distinction between distributions of targets and clutters. For PolSAR data, a new detector is proposed, which is the product of multiply distinction parameters from three polarimetric channels. A ship detection method based on the detector is also developed, and experimental results demonstrate the efficiency of the proposed method.
