Ultra-high resolution airborne SAR imaging of vegetation and man-made objects based on 40% relative bandwidth in X-band
Abstract
The latest upgrade of the airborne X-band SAR/GMTI sensor PAMIR of Fraunhofer FHR to a simultaneous bandwidth of 3.6 GHz according to a relative bandwidth of 40 % enables ultra-high resolution capabilities in SAR imaging. The actual sensor specification is described and some examples of SAR images with urban and rural scenarios offering a geometrical resolution down to 4 cm times 1.5 cm (range; azimuth) are presented.
