Abstract	The Differential Synthetic Aperture Radar Interferometry (D-InSAR) is widely used in large-scale ground deformation monitoring such as crustal deformation, seismic changes, land subsidence, landslides, volcanic deformation, glacial movement. In this paper, The deformation analysis based on two-pass differential and three-pass differential InSAR is done. We have shown that the analytic results by the three-pass differential method is better. The quality of result may be effected in phase unwrapping in two different methods. The deformation fields obtained by two different differential methods have been compared with traditional methods. With the changes in topographic factor, climatic conditions and vegetation types, the coherence effect is different, results have been given. It is not easy that the strong coherence is satisfied in three SAR images in the same time. Therefore, the optimizing methods depend on the purpose of application and the characteristics of studied area.
