Bistatic SAR Experiment with the Ingara Imaging Radar: Preliminary Results

The Ingara fully-polarimetric X-band airborne imaging radar system has recently been upgraded to conduct experimental SAR data collections in a bistatic geometry. Initial trials of the new bistatic SAR system were conducted in late 2007: these involved operation of the airborne radar in a fine-resolution (600 MHz bandwidth) circular spotlight-SAR mode, in conjunction with a newly-developed fully-polarimetric stationary ground-based bistatic receiver. This paper gives an overview of the Ingara bistatic SAR system, discusses the experiments and data processing, and presents initial experimental results.
