针对极化合成孔径雷达（polarimetric synthetic aperture radar，PolSAR）的目标检测，提出了一个杂波区分度参数。通过构造一个包含了部分杂波像素及目标区域像素的集合，提取的杂波区分度参数衡量了该集合的均匀性，从而反映出目标区域与杂波分布的区分度。对于全极化数据，通过将3个极化通道的杂波区分度参数相乘，提出了用于舰船检测的检测量，并进行目标检测的方法。实验结果表明，所提方法实现了很好的目标检测性能。

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 tar-gets and clutters.For PolSAR data,a new detector is proposed,which is the product of multiply distinction pa-rameters 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.
