InSAR干涉条纹图滤波方法比较与分析——以南屯矿区为例

Analysis of InSAR Interferogram Filtering Method: a Case for the Nantun Mining Area

以南屯矿区为例,对TerraSAR-X卫星获得的南屯矿区实测干涉条纹图分别进行均值滤波、中值滤波、圆周期均值滤波、圆周期中值滤波以及基于小波变换的滤波处理,详细比较和分析了各种滤波结果,最终通过残留点、等效视数等相关指标,得出圆周期中值滤波是上述方法中选择最适合该矿区的干涉条纹图滤波方法。

In this paper, the interferogram was fihered by mean filtering method, median filtering method, periodic pivoting mean filtering method, periodic pivoting median filtering method, and filtering method based on wavelet transform, which were acquired by TerraSAR-X satellites in Nantun mining area. Then we determined which was the best filtering method in this area through a series of indicators, such as residues.
