Simulation of facade reference data for 3D SAR algorithms

This paper presents preliminary results of a workflow for generating facade reference data as a basis for evaluating the localization capability of 3D SAR algorithms (tomographic or radargrammetric). In this context, the required facade model is provided based on photogrammetric reconstruction and terrestrial surveys with cm-accuracy. The SAR simulator RaySAR is used to provide the phase center positions of prominent scatterers in the world coordinate system. Simulation results in 2D and 3D are presented for a facade located at the TUM campus in Munich to indicate the necessary level-of-detail for the modeling step.
