基于SARscape的干涉叠加在地表形变监测中的应用
|
摘要
地表形变主要表现为地震形变、地面沉降、山体滑坡等,由InSAR技术发展而来的干涉叠加通过挖掘时间序列SAR图像获取mm级的形变信息。本文介绍了干涉叠加技术的基本原理和技术流程、基于永久散射体的方法,利用2008年～2010年的23幅Cosmo-skymed数据对北京奥林匹克公园内的主要区域进行了地表形变的监测。
Land surface deformation include earthquake deformation、landslide and surface subsidence etc.The interferogram stacking technique,extending SAR interferometry to the analysis of large sets of multi-temporal acquisitions,enables to get the displacement information with few millimeters measurement.This paper introduces the fundamental and technique process of interferogram stacking.And we take the Beijing Olympic park as study area to do the surface deformation monitoring using 23 Cosmo-skymed data between 2008 to 2010,based on PS technique.
