Extraction of building height based on modified double scattering model from single SAR image

Typical features in SAR image like the bright line cause by double scattering are important datum in building height extraction, especially for the extracting method form a single SAR imagery. Its accuracy will affect the extraction result. In this paper, against to the imprecise of double scattering model, we modified its geometrical relationship. By using this model, we proposed a method with the usage of pixel interpolation and image correlation to extract the height of rectangular and cylindrical buildings.
