摘　　要：按照数据获取方式的不同,地基干涉雷达工作模式可分为连续测量模式和间断测量模式。针对目前间断测量中存在的图像失相干问题,提出了一种基于SAR图像配准的技术方法,在SAR图像干涉处理前,通过图像合成和图像配准,有效提高了SAR图像的相干性。对彭水县联合乡马岩危岩区域的3个监测点的间断测量数据进行分析,结果表明:经过图像合成与配准,观测区域的形变具有较好的延续性,雷达形变测量结果与全站仪测量结果较为接近。该间断测量方法可有效提高地基干涉雷达的形变测量能力。According to the different ways of data acquisition,SAR working mode can be divided into continuous measurement mode and discontinuous mode.Aiming at the problem of image incoherence in discontinuous measurement,this article proposes a method based on SAR image registration.Before SAR image interference processing,the coherence of SAR image is effectively improved by image synthesis and image registration.The article analyzes discontinuous measurement data of three monitoring points in Mayan,Lianhe Township,Pengshui County.The results show that the deformation of the observation area has good continuity after image synthesis and registration,and the SAR deformation measurement results were close to the total station measurement results.The discontinuous measurement method can effectively improve the deformation measurement ability of GB-SAR.
