Interferometric SAR phase unwrapping using Green´s formulation

Any method that permits retrieving full range (unwrapped) phase values starting from their (-π,π) determination (wrapped phase) can be defined as a phase unwrapping technique. This paper addresses a new procedure for phase unwrapping especially designed for interferometric synthetic aperture radar applications. The proposed algorithm is based on use of Green´s first identity. Results on simulated as well as on real data are presented. They both confirm the excellent performance of the procedure
