Abstract:

In this Letter, a method is proposed for interferometric synthetic aperture radar (SAR) phase unwrapping based on image segmentation. An auxiliary phase map was generated and the interferometric phase was divided into many connected regions without discontinuity by separation and combination operations. A local optimal strategy was used to combine these regions with as few discontinuities as possible. The coherence map is not necessary. The authors compared the proposed method with Goldstein's branch-cut algorithm (BC) and the weighted multi-grid algorithm (WMG), demonstrating the effectiveness of the proposed method.
