Latest Upgrades On SAR-Light, Onera’s UAV-Embedded SAR Tool

ONERA, the French aerospace lab, has been developping a drone-embedded SAR imaging tool, SAR-Light, After three years of developpments, we now. Now that it has been fully characterized in both X- and C-band and in full-polar, and demonstrated to reach similar imaging capabilities as larger carriers despite a 6kg payload, we focus on more operational use cases. In this paper we display recent results for target characterization and scenery inspection, which demonstrate the high repetability of image projection from one flight path to another. The limited payload however puts high constraints on the inertial measurement unit, although trajectory reconstruction is critical for synthetic aperture radars. In this work we demonstrate the high reproducibility of our results by caracterising non coherent change detection at short range with very diverse objects. We the introduce a recent demonstration the latest upgrade of our system with a new inertial measurement unit.
