An airborne demonstration for high-resolution wide-swath spaceborne reflector SAR systems

Intensive research is currently concentered at the field of Space-borne Reflector Synthetic Aperture Radar (SAR) Systems for high resolution wide-swath application. To meet the requirement of high resolution wide-swath SAR system, multichannel systems based on Reflector SAR system is introduced, for example, Tandem-L/NISAR Mission. This paper introduces an air-borne SAR system based on Reflector SAR system, and takes several flight experiments. The results show that using Digital beam forming (DBF) algorithm, a simultaneous improvement in azimuth resolution and wide swath can be achieved.
