摘　　要：极化合成孔径雷达(SAR)能够获取目标的全极化信息,在对地观测、灾害评估、侦察监视等民用和军用领域得到广泛应用。国内主要高校、中科院、工业部门和用户单位在该领域开展了卓有成效的工作,取得一大批标志性研究成果。该文简要综述了极化SAR成像解译识别领域的主要研究进展。在解译层面,主要介绍了极化目标分解和极化旋转域解译等理论方法的研究进展。在应用层面,结合研究团队的工作,探讨了上述理论方法在舰船检测、地物分类和建筑物损毁评估等领域的应用成效。最后,对极化SAR目标解译识别技术的研究进行了展望。Polarimetric Synthetic Aperture Radar(SAR), which can acquire fully polarimetric information, is widely used in civilian and military fields, such as earth observation, damage assessment, and reconnaissance.Major Chinese universities, the Chinese Academy of Sciences, the industrial sector, and user units have conducted research in this field and obtained numerous remarkable achievements. This work reviews the recent progress of research in the field of polarimetric SAR imaging interpretation and recognition. For target scattering interpretation, theories of polarimetric target decomposition and polarimetric rotation domain interpretation are introduced. For polarimetric SAR application, the technologies of ship detection, land cover classification, and building damage assessment, which are based on the interpretation tools, are summarized in combination with the authors’ own research. Finally, the future development perspectives of polarimetric SAR interpretation and recognition are briefly discussed.
