摘要 对极化SAR(合成孔径雷达)图像分类进行综述。首先建立简略的极化SAR图像分类技术发展流程,并对国内外研究机构在该领域的主要研究成果进行归纳;然后对用于极化SAR图像分类的众多特征进行分类整理,指出其物理意义及在图像分类中的优缺点,并从有监督和无监督的角度综述了现有的极化SAR图像分类方法;最后对极化SAR图像分类存在的问题进行归纳,并指出将来的研究方向。 A review of polarimetric SAR ( synthetic aperture radar) image classification is provided. First, a summary development course of polarimetric SAR image classification is introduced, and primary research results are concluded. Second, many features, with their physical meanings and merits and deficiencies in polarimetric image classification, are discussed. Third, many algorithms for supervised and unsupervised classification are summarized. Finally, existing problems and further research directions are pointed out.
