Improved branch-cut phase unwrapping strategy based on dynamic adjacent table

Improved branch-cut phase unwrapping strategy based on dynamic adjacent table

Phase unwrapping (PU) is a key step of interferometric SAR signal processing. The accuracy of the unwrapping phase directly affects the accuracy of the digital elevation model (DEM). The traditional path-integral methods and global-planning methods cannot take into account both PU accuracy and proce...
