چکیده

In the recent past, airborne Synthetic Aperture Radar (SAR) remote sensing has witnessed several principal and technical improvements. In particular, spatial resolution has been increased significantly, polarimetric SAR, polarimetric interferometric SAR, and tomographic SAR were introduced, and repeat-pass interferometric SAR was developed for airborne SAR sensors. These advances have made possible numerous new applications, including urban structure and object detection and characterization. In this paper we describe current challenges in the continued development of airborne SAR systems. We illustrate the description by research work conducted at Berlin University of Technology in the time period from 2002 to 2005.
