Abstract :
Comparison analysis of two interferograms unwrapping approaches has been done. Computer modeling of InSAR phase reconstruction methods and analysis of dependence of errors of the unwrapping on phase noise level are performed. The analysis of phase unwrapping approaches for SAR interferograms has been achieved by comparing two popular methods like Residue-cut method and Least squares method.
