Radar Shape From Shading (SFS) has been an active research topic on the processing of airborne and spaceborne single polarized SAR images during last two decades. The second generation of spaceborne SAR systems, such as Radarsat-2, will obtain fully polarized information about the ground targets. As the quadrature polarized (quad-pol) SAR images provide useful information on surface roughness and backscatter properties, this research intends to apply the SFS technique to the quad-pol SAR image to obtain topographic information. The technique is tested on the Canadian C/X-SAR (carried on Convair-580) quad-pol data, which is used as simulated sample data of potential Radarsat 2. The results (elevation profiles) are validated with the ground truth elevation profiles, generated from Digital Elevation Model of the area. The geometric accuracies are analyzed.
