N2 - Traditional differential synthetic aperture radar tomography (D-TomoSAR) is difficult to fully reflect the actual deformation of ground, because it can only capture onedimensional (1-D) deformation along the line of sight (LOS) of the SAR. An extended D-TomoSAR model for retrieving the three-dimensional (3-D) deformation parameters of ground is proposed in this paper. The 3-D deformation parameters in the directions of azimuth, range, and elevation are firstly introduced into the traditional D-TomoSAR signal model. Then the sparse reconstruction technique is used to reconstruct the scatterers' elevation and deformation parameters. Simulations and experimental results with semireal data verify the effectiveness of the proposed signal model and algorithm.
