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 new generation of space-borne high resolution SAR sensors such as TerraSAR-X, SAR-Lupe or CosmoSkyMed provides SAR images of 1-3m spatial resolution or even below in special spotlight modes. Naturally, the development of methods to automatically derive detailed cartographic information of both rural and urban areas from this kind of data is a major(More)
The achievable spatial resolution of state-of-the-art synthetic aperture radar (SAR) sensors enables the analysis of urban areas. The appearance of buildings in magnitude images is governed by effects of the inherent oblique scene illumination, such as layover, radar shadow and salient lines of bright scattering caused by direct reflection or multipath(More)
The improved ground resolution of state-of-the-art synthetic aperture radar (SAR) sensors suggests utilizing this technique for the analysis of urban areas. However, building reconstruction from SAR or InSAR data suffers from consequences of the inherent oblique scene illumination, such as foreshortening, layover, occlusion by radar shadow and multipath(More)
One of the main future tasks in the field of reconnaissance and surveillance is the data fusion of heterogeneous systems. For this purpose sensor data of airborne and spaceborne systems, which acquire the data from the same scene, with different spatial and spectral coverage are used. The use of different sensors enables the exploitation and the extraction(More)
