Passive Space-Surface Bistatic SAR for local area monitoring: Primary feasibility study

This paper presents a new topology for a sub-class of bistatic SAR, called Space-Surface Bistatic SAR (SS-BSAR). This new topology comprises Global Navigation Satellite Systems (GNSS) as transmitters of opportunity and a stationary receiver on the ground. It is shown that such a system is promising for local area monitoring, and its very basic radar performance (power budget, resolution) is assessed.
