High resolution radar imaging of urban areas

New synthetic aperture radar (SAR) sensors on satellites like TerrsSAR-Xallow flexible mapping with a large coverage or a high resolutionof about one meter. Leading-edge airborne SAR sensors provide spatialresolutions on the order of a decimetre. In such data, many featuresof urban objects can be identified, which were beyond the scope ofradar remote sensing before. But, SAR images are often really difficultto be interpreted: the presence of speckle as well as of some distortioneffects, like shadowing and layover, makes the analysis of this kindof image complex. The impact of high resolution SAR data on the analysisof urban scenes and typical SAR effects are discussed. Examples forthe appearance of buildings and other man-made objects are given..Thebenefit of SAR-simulation is addressed and examples are shown. Finally,typical problems in SAR smulation is discussed     «
