Building reconstruction from high-resolution InSAR data of urban areas
The improved ground resolution of state of the art synthetic aperture radar (SAR) sensors suggests to use this technique for the analysis of urban areas. The quality of 3D reconstruction of buildings from SAR or InSAR data is limited by phenomena caused from the inherent oblique scene illumination of SAR sensors. Geometric constraints of the impact of the mentioned SAR phenomena on the visibility of buildings are derived. In this paper an approach for the detection and reconstruction of buildings from an InSAR data set is proposed. The analysis is carried out in an iterative manner. Intermediate results are used as a basis for simulations of InSAR data. The simulation results are compared with the real imagery. Deviations between the simulations and the real data are eliminated step-by-step. The approach is demonstrated for an InSAR data set of a building group in an urban area.
