Potential of very high resolution SAR interferometry for urban building analysis

In this paper, the potential of very high resolution interferometric SAR imaging for urban building analysis will be demonstrated. Interferometric analysis based on very high resolution SAR images (down to sub-decimetre resolution) acquired over urban areas will be presented. The corresponding data was acquired in airborne singlepass and multi-pass configurations using the X-band SAR/GMTI demonstrator PAMIR of Fraunhofer FHR. It is shown that the advantage of single-pass interferometry for exploiting the third dimension can considerably be enhanced by using very high resolution multi-pass configurations with height sensitivities of up to 1000 deg/m.
