Paper Abstract

Phase unwrapping is the key step in deriving topographic information from Interferometric SAR. We propose a region-cutting InSAR phase unwrapping method based on Shortest Distance First Principle(SDFP), the interferogram is cut into the residue regions which contain all the residues and the non-residue regions which contain no residue. The pixels of the non-residue regions are unwrapped using modified Itoh's method firstly while the residue regions have been isolated, then region-growing strategy of region-growing phase unwrapping algorithm is applied to unwrap the pixels of residue regions from the unwrapped non-residue regions. The test performed on the real wrapped phase data obtained from the interferometry of a pair SAR images shows the proposed algorithm is fast and efficient even in low-quality regions.
