Abstract:
Estimation of topography for the generation of digital elevation models requires unwrapping of the interferometric phase to obtain the absolute phase. When the topography changes rapidly or the geometry is unfavourable, phase unwrapping cannot always be performed correctly leaving gaps or errors in the digital elevation model. Based on taking the differential phase between two subband interferogramsn, the delta-k technique can artifically increases the height of ambiguity by up to several orders...     »
