Passive GNSS-Based Multistatic SAR: First Experimental Results

Abstract

This paper shows experimental methods and results on passive multi-static Synthetic Aperture Radar (SAR) using Global Navigation Satellite Systems (GNSS) as transmitters of opportunity. The paper describes details of an experimental campaign designed for this purpose, where a total of thirty-six bistatic images were obtained from a single receiver and two satellites belonging to two different constellations (GPS and Galileo). Finally, multi-static imagery obtained using non-coherent combination methods is presented.
