First result of bistatic forward-looking SAR with stationary transmitter

With appropriate geometry configurations, bistatic Synthetic Aperture Radar (SAR) can break through the limitations of monostatic SAR on forward-looking imaging. Thanks to such a capability, bistatic forward-looking SAR (BFSAR) has extensive potential applications. In this paper, we present a vehicle-borne BFSAR experiment, including the imaging principle, system setup, echo property and data processing result. In the experiment, the transmitter is located stationarily besides the moving receiver. The transmit and receive antennas both point to the up forward-looking area to illuminate a point target. To the authors' knowledge, this is the first result of BFSAR with stationary transmitter in the world right now.
