Interferometric Synthetic Aperture Radar (InSAR) is a powerful technique for precise topographic
mapping. However, owing to the side-looking SAR imaging geometry, geometry distortions appear in mountainous
scenarios. Because of phase discontinuities or the absence of a valid phase, it is difficult to recover accurate DEM
in such areas with single-aspect InSAR data. Fusion of two or more different aspects of InSAR data can deal with
this problem in practice. Experiments using two antiparallel aspects of airborne InSAR data are carried out based on this idea.
