摘要 针对边缘检测中极化信息利用率不高的问题,提出了一种结合自适应最优对比增强与均值比的合成孔径雷达边缘检测新方法,并分析新算法特性后,推导了其快速版本。实验结果表明,新方法具有更好的检测性能。 Aiming at improving the utilization of polarimetric information, a new edge detector for polarimetric synthetic aperture radar（PoLSAR） images based on adaptive optimal polarimetric contrast enhancement and ratio of averaging was proposed in this paper. The optimal polarization is adaptive to window location and edge templates. Therefore the new method is robust. Experimental results of simulated and real PolSAR data both revealed that the performance of the new detector was improved.
