Radar imaging of urban areas by means of very high resolution SAR and interferometric SAR

In remote sensing applications the monitoring of urban areas by means of SAR sensors has been grown to a valuable and indispensable tool. Whereas SAR imaging with a spatial resolution down to one meter is widespread, a resolution down to 10 cm and below is offered only by a very few SAR sensors worldwide. In this contribution the potential of high resolution and very high resolution radar imaging of urban areas by means of SAR and interferometric imaging will be demonstrated and discussed. Limits of these techniques and open problems will be addressed as well. The corresponding data were acquired with PAMIR, the X-band SAR/GMTI demonstrator of FGAN-FHR.
