Abstract
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 problem doesn’t have a unique solution due to phase discontinuity caused by the phase noise and aliasing. A phase unwrapping algorithm for interferometric 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.
