摘　　要：三维合成孔径雷达在测绘制图、防灾减灾等诸多领域有应用潜力,已经成为SAR的重要研究方向。为减少三维SAR的观测次数或天线阵元数量,推动三维SAR的应用和发展,中国科学院空天信息创新研究院牵头研制了微波视觉三维SAR实验系统,旨在为微波视觉SAR三维成像提供实验平台和数据。该文针对微波视觉三维SAR实验系统及其全极化数据处理方法进行介绍,涵盖了极化校正、极化相干增强、极化约束三维成像、三维融合可视化等全流程的关键步骤。基于发布的SAR微波视觉三维成像全极化数据集,给出了三维成像结果示例,验证了微波视觉三维SAR实验系统的全极化性能以及处理方法的有效性。该文发布的数据集将为SAR三维成像研究提供良好的数据条件。Three-Dimensional(3D)Synthetic Aperture Radar(SAR)holds great potential for applications in fields such as mapping and disaster management,making it an important research focus in SAR technology.To advance the application and development of 3D SAR,especially by reducing the number of observations or antenna array elements,the Aerospace Information Research Institute,Chinese Academy of Sciences,(AIRCAS)has pioneered the development of the full-polarimetric Microwave Vision 3D SAR(MV3DSAR)experimental system.This system is designed to serve as an experimental platform and a source of data for microwave vision SAR 3D imaging studies.This study introduces the MV3DSAR experimental system along with its full-polarimetric SAR data set.It also proposes a set of full-polarimetric data processing scheme that covers essential steps such as polarization correction,polarization coherent enhancement,microwave vision 3D imaging,and 3D fusion visualization.The results from the 3D imaging data set confirm the full-polarimetric capabilities of the MV3DSAR experimental system and validate the effectiveness of the proposed processing method.The full-polarimetric unmanned aerial vehicle-borne array interferometric SAR data set,released through this study,offers enhanced data resources for advancing 3D SAR imaging research.
