This paper presents research results in Space-Surface Multistatic Synthetic Aperture Radar (SS-MSAR) with non cooperative GPS satellites. The goal of this paper is to characterize such a system in an ISAR context, with a moving ground target. Point Spread Function (PSF) are defined and used in this work to estimate the performance in term of resolution. These criteria are computed, and compared, for several scenarios with targets of different velocities.
