摘要：The objective of this paper is to provide an update on two programs which have been evolving recently that will have significant impact on several geomatics application areas requiring 3D information over extended areas. The first program relates to the creation of nation-wide and continental-scale DEM databases using airborne Interferometric SAR (InSAR) at a level of detail intermediate between that of airborne lidar and space-borne systems. This program is operational and well advanced in its goal. The second program is developmental, and concerns a first-of-its-kind airborne, single-pass L-Band, fully polarimetric InSAR (PolInSAR) system. The primary goal of this research is to determine how well ground elevation can be extracted beneath forest canopy of different types in the absence of temporal decorrelation effects. Some preliminary results are presented here
