Two-dimensional phase unwrapping problem was considered. Phase unwrapping is a key step of generating digital elevation model with the use of topographic radar interferometry. Difficulty of phase unwrapping problem is caused by unknown location of discontinuities on the interferogram and large interferogram sizes. On the base of Bayesian approach the mathematical model of the phase slopes on radar topographic interferograms was developed. Phase unwrapping may be considered as an optimization problem. For this statement of the problem a mathematical method based on the developed mathematical model was proposed. The computational experiment confirmed practical value of the obtained results.
