Sar-Light, A Versatile Sar Sensor on Uav Platform for Target Characterization

ONERA, the French aerospace lab, has been developping over the past two years SAR-Light, a drone-embedded SAR tool. Our aim is to achieve equivalent performances to those of SETHI, ONERA’s plane embedded SAR tool [1], while enabling more flexible acquisitions. SAR-Light is now able to reach an 0.08 meter resolution (in X-band) without the need for autofocus, and has proven capable of performing advanced SAR modes, both in X- and C-band, and in full-polar. Here we display milestones of the development of SAR-Light, along with a few of its recent achievements during flight test campaigns, and more operational use cases.
