摘要

增强空间差分(ESD)技术是一种用于大范围小尺度地面变形监测的新型处理链。处理的核心是空间差分(SD)步骤，该步骤通过空间差分对平均变形速度和残余地形进行快速初步估计。我们展示了将ESD算法应用于ERS和ENVISAT相邻轨道上收集的数据所获得的结果。

Deformation monitoring over a large area via the ESD technique with data takes on adjacent tracks

Enhanced spatial differences (ESD) is a new processing chain for monitoring ground deformations at small scale over wide areas. Core of the processing is the spatial differencing (SD) step that performs a quick preliminary estimation of the mean deformation velocity and residual topography via spatial differences. We show the results achieved by applying the ESD algorithm to data collected over adjacent tracks for ERS and ENVISAT.
