Beschreibung
Zusammenfassung:	The phase unwrapping device 10 includes coordinate transformation means 11 for transforming coordinates of a map including height information into SAR image coordinates, weight calculation means 12 for determining a place, from the map whose coordinates are transformed into the SAR image coordinate, where phase discontinuity may occur in a phase different image generated from two SAR images and attaching a weight to the place where it is determined that phase discontinuity may occur, and phase unwrapping means 13 for performing phase unwrapping for the phase difference image using the weight.
