Efficient estimation of the interfermetric phase for distributed scatterers is essential for interfermetric synthetic aperture radar (InSAR). Methods have been developed in recent year to retrieve deformation information in interferometric stacks focused on distributed scatterers. Compared to the conventional approaches, those methods focus on homogeneous pixels referring to distributed scatterer and consider all possible interferograms in interfermetric phase estimation, which is preserve the physical meaning of the distributed scatterers. In this paper, different methods are presented and applied to real data, and the corresponding results are compared and analysed.
