Investigating Ground Subsidence in Beijing by Using Interferogram Stacking InSAR
This paper presents an application of interferogram stacking InSAR to investigate the ground subsidence in Beijing. In order to improve the ensemble coherence levels between SAR images, a small baseline interferogram strategy was adopted and the appropriate search windows sizes were selected in coregistration process. The measurement result indicates that a ground subsidence zone appeared, respectively, in Chaoyang and Tongzhou districts and there was almost no ground subsidence within the 5th Ring Road during the period January, 2009 to January, 2010.
