| Abstract: | The application of conventional differential SAR interferometry (DInSAR) is limited because of temporal and spatial decorrelation. Although the permanent scatterers (PS) method could deal with the problem of decorrelation and phase delay, it must be based on a Darge number of SAR images (generally more than 25). However, the small baseline subsets (SBAS) method has the advantage. So, in this paper, 8 of SAR data acquired from January 2008 to August 2010 by the ENVISAT satellite are taken as the test data and then, the deformation of Taiyuan city is obtained with the SBAS method, and the maximum deformation rates of three sites:Wanbolin, Wujiabao and Xiaodian are -27.11 mm/a, -55.92 mm/a and -67.61 mm/a respectively. The results of deformation rate and time series deformation maps are consistent with the previous results,thus it has verified that the SBAS method is feasible to monitor surface deformation. |
