Abstract
With the increasing availability of high resolution SAR imagery like RADARSAT-2 and TerraSAR-X, it becomes interesting to investigate the potential of this type of data for urban applications. There is however a great obstacle in using SAR imagery of urban areas: the corner reflector or "cardinal effect" problem. It is greatly problematic when multiple images of the same scene are taken from different azimuth angle. We propose a novel framework to overcome this problem by using contextual information about road orientation and building position to correct higher than normal pixel intensity caused by corner reflectors.
