This paper investigates the potential in using a passive multi-static Synthetic Aperture Radar (SAR) with Global Navigation Satellite Systems (GNSS) as transmitters of opportunity. The motivation for this research is based on the concept that a non-coherent combination between multiple bistatic images, obtained by satellites with essentially different angular separations, may yield multi-static imagery with a drastically improved resolution in the range dimension. This concept is confirmed by analytically deriving the multi-static Point Spread Function (MPSF) for this topology.

Abstract
This paper investigates the potential in using a passive multi-static Synthetic Aperture Radar (SAR) with Global Navigation Satellite Systems (GNSS) as transmitters of opportunity. The motivation for this research is based on the concept that a non-coherent combination between multiple bistatic images, obtained by satellites with essentially different angular separations, may yield multi-static imagery with a drastically improved resolution in the range dimension. This concept is confirmed by analytically deriving the multi-static Point Spread Function (MPSF) for this topology. The validity of the analytical results is verified with experimental data. © VDE VERLAG GMBH · Berlin · Offenbach, Germany.| File | Dimensione | Formato | |
