The problem of digital elevation models generation from interferometric pairs of SAR images is considered at the stage of phase un-wrapping. The algorithm of phase unwrapping, that allows to provide high accuracy of relief phase surface reconstruction at the case of complex scenes due to analysis of weighted least squares method residuals and use of reference relief data, is proposed. The comparison of classical phase unwrapping methods and proposed algorithm accuracy has been performed. The proposed approach can significantly improve the accuracy of the deployment phase in the interference patterns with a complex plot.
