Phase unwrapping is the most complicated and unreliable stage of interferometric data processing, which is often used in remote sensing techniques. For real radar scenes, the phase unwrapping prob- lem doesn't have a unique solution due to phase discontinuity caused by the phase noise and aliasing. A phase unwrapping algorithm for interfer- ometric phase images based on 3d-phase function branch merging and cutting is proposed. It improves reliability of the unwrapped phase used for digital elevation models generation.
