  • In order to decrease the negative effects of spatio-temporal decorrelation in differential synthetic aperture radar interferometry(DInSAR),a method for analyzing the time series of ground deformation with a network formed by connecting adjacent permanent scatters(PSs) was proposed.With this method,interferometric combination is formed by considering both temporal-and spatial-baseline threshold,linear and non-linear motions can be extracted and separated from the PS-networking model,and the entire time series of ground deformation can be reconstructed by the singular value decomposition.An experiment was performed using 39 ERS-1/2 C-band SAR images,acquired from 1992 to 2000,related to the Phoenix region of the United States.The experimental results show that the proposed method is feasible and effective.
