摘要(Abstract)：

针对InSAR-BM3D滤波在干涉图条纹密集、噪声严重情况下，存在的对干涉条纹保护较差、易丢失细节信息的问题，该文利用圆周期中值滤波对条纹频率估计方法进行优化以提高条纹频率估计精度，并利用优化的条纹频率方法对InSAR-BM3D滤波方法进行改进。为验证本文改进滤波方法的有效性，分别进行模拟数据与真实数据的滤波实验，并将改进滤波方法与未改进InSAR-BM3D滤波以及常用的Lee滤波、Goldstein滤波、小波硬阈值滤波、小波软阈值滤波进行滤波结果的定性和定量比较。结果表明，改进滤波方法在保持InSAR-BM3D滤波高效抑制噪声优势的同时，提高了对干涉条纹边缘和细节的保护能力，能获得更好的滤波效果。
