Abstract :
In this paper, a model-based approach for geometry extraction of the rectangular building is proposed based on the scattering model. According to the principle of SAR and the scattering mechanisms, the scattering model is deduced according to the ray perspective, including single, double and triple scattering. The double-bouncing scattering region is chosen as a fixed reference point in the matching process. This approach deals with the geometry extraction by using the layover, shadow and multi-path scattering information together. Experiments are implemented on ESR SAR data, which tests the validity of the approach proposed.
