Concept Study Of Future Land Observation Satellite Techniques When Utilizing Khatri-Rao (Kr) Product Array Processing

Future satellite SAR (SAT-SAR) will be required to provide more value-added observations in addition to constellation services. The SAT-SAR and sub-missions will need to be more sophisticated. This paper proposes applying KR product array processing to Digital Beam Forming (DBF) and synthetic aperture processing for the azimuth of the SAT-SAR. This paper presents the initial results of simulations for both high resolution and wide swath with about twice the Rx effective aperture length.
