Surface Deformation Detection by Small Baseline Sar Interferometry in Cangzhou Coastal Zone

We collaborate with Department Of Land And Resources of Hebei Province and detect the Surface deformation by InSAR SBAS processing. SAR data covered the coast of Hebei Cangzhou (ENVISAT IS2 & RADARSAT-2 W1 beam,2003-2013) are acquired. Image interpretation and change detection of buildings base on middle and high resolution optical images, provides prior background knowledge for InSAR processing in this case. InSAR results and fieldwork show there is a strong relationship between the effect of industrial expansion and the location of land subsidence.
