This paper investigates InSAR central problem and presents its noise characteristics analytically. A phase estimation method is proposed for InSAR surface deformation studies which performs noise filtering task by order-statistical filter base on the correlation weight of multi-acquisition. Such varying filter help preserve the information i.e. the phase discontinuities pixels. Then, iterative-smoothing filter is applied to the unwrapped phase image. Proposed approach is validated by simulated and real data. Other phase estimation methods also implemented for comparative studies. Achieved results demonstrated the efficiency of proposed method. |
