Design of a millimetre Synthetic Aperture Radar (SAR) onboard UAV's

This paper describes the design for an experimental short-range (2 Km) high-resolution (30 x 30 cm
²
) synthetic aperture radar (SAR) sensor in the millimetre wave band to take it onboard unmanned aerial vehicles (UAV). The novelty lies on the establishment of new and very demanding requirements induced by the need of being onboard low cost aerial platforms and so, susceptible of been employed in numerous military and civil applications, providing the basic advantage of these sensors against electro-optics: the possibility of using them at any time (night and day) and practically under any meteorological condition.
