| Abstract: |
With the emerging of multi-frequency InSAR system, extraction of 3-D and variation information of earth surface using multi-frequency InSAR data has drawn more attention. Methods based on Maximum-Likelihood Estimation (MLE), combining with some conventional phase unwrapping algorithm can be used to achieve this purpose. In this paper, MLE integrated with weighted multigrid phase-unwrapping method for high-sloped terrain profile reconstruction is presented and studied in detail. The performance of this method is also analyzed. Experiment result using simulated InSAR data shows that the method can be used to reconstruct high-sloped terrain with relatively high accuracy. |
