Abstract

Phase unwrapping is an important part in the process of InSAR signal processing. When ground-based SAR is used for multistage mountain slope deformation monitoring, the mountain slopes are always separated by slope ladders. So the interferometric phase of every slope must be unwrapped by path-following methods respectively. In view of the multistage slope phase unwrapping, this paper proposed a mask branch-cut segmentation phase unwrapping algorithm through improving on the Goldstein's mask branch-cut algorithm. Then a deformation monitoring experiment for multistage mountain slope was carried out, which is to verify the validity and feasibility of the unwrapping algorithm.
