Multi-perspective GNSS-based passive BSAR: Preliminary experimental results

This paper presents preliminary experimental results on passive bistatic SAR imagery acquired at multiple bistatic geometries. Images were obtained using a Space-Surface bistatic SAR topology, with navigation satellites as transmitters of opportunity and a fixed receiver. Details of the experimental program are given and the obtained bistatic images are presented and analyzed. It is demonstrated that diverse scattering effects can be seen for the same scene objects, when viewed from different angles. Such information could potentially be used to increase the amount of information for a given scene.
