ONERA DRIVE Project

摘要

Future UAV employment in the civilian areas ofsurveillance (pollution, natural risks prevention, fire prevention),monitoring (traffic control, environmental monitoring, earthobservation) and communication relays becomes unavoidable.Many payload configurations may be used in UAV operations,but compared to systems working in other spectral regions (suchas optical or infrared sensors), radar has the main advantage tobe able to operate in all-weather condition.A concept of 3D imaging radar in Ka-Band radar is presented inthis paper. A demonstrator of this radar has been integrated intounder-wings pods that are fixed on a STEMME S10VTmotorglider. This radar concept combines real aperture in thecross-track direction, by the antennas geometrical aperture, andsynthetic aperture in the along-track direction, realized with theaircraft motion.The DRIVE radar has been developed and built to fly on boardan UAV vehicle, but current airplane used for testingapplications is a STEMME S10-VT motorglider. The radardefinition will be detailed, and first results obtained on Fall 2006will be exposed.
