3D models for SAR simulation
For comparing SAR simulators, identical 3d models have to be used to allow a meaningful comparisson. In T. Balz, H. Hammer, S. Auer, "Potentials and limitations of SAR image simulators – A comparative study of three simulation approaches," ISPRS Journal of Photogrammetry and Remote Sensing 101, 102-109, we used two models for this purpose. The first model is a simple 10x10x5 m building. The second model is a silo. Both models can be found and downloaded here.
