— Modern space borne SAR sensors provide geometric resolution of one meter, airborne systems even higher. In data of this kind many features of urban objects become visible, which were beyond the scope of radar remote sensing only a few years ago. However, layover and occlusion issues inevitably arise in undulated terrain and urban areas because of the… (More)
The improved ground resolution of state-of-the-art synthetic aperture radar (SAR) sensors suggests utilizing SAR data for the analysis of urban areas. Building recognition however suffers from the consequences of the inherent side-looking viewing geometry of SAR, particularly occlusion and layover hinder the analysis. Usually extracted layover regions are… (More)
