Abstract

Interferometric synthetic aperture radar interferometry (InSAR) phase unwrapping is influenced by the terrain factors, how to consider the terrain factors especially the complex ones is meaningful to the unwrapping algorithm. In order to solve this problem, based on the terrain phase statistical information, this paper proposes a phase gradient estimation(PGE) model applied for the additional constraint condition to the nonlinear least squares phase unwrapping. It involves the model not only eliminates noise influence, but also considers the terrain factors. Finally, real data unwrapping experimental results, comparing the proposed algorithm with classical approaches, illustrates the effectiveness the PGE phase unwrapping algorithm could be used to eliminate the effect of topography variation in the unwrapping process.
