A four-element 80-GHz luggage scanner based on the synthetic aperture radar principle

  • During recent years different types of millimetre-wave and terahertz-scanners have been developed, as well radar-based as passive radiometers. Mainly body scanners were in the focus of research. Although luggage and parcels are sufficiently inspected using X-ray techniques, the use of millimetre wave technology also for this application offers some advantages. Among them are easy deployment at any place, due to compact geometry, possible miniaturization of sensors and stand-off operation without any radiation hazard. Also the better contrast of dielectric material including explosives are of considerable advantage, not to neglect, that scanning is possible while the owner keeps the luggage in his hands. This allows tracking a piece of luggage together with its owner without losing their mutual relation. To allow a fast scanning, an array solution is investigated using state-of the art devices at the 80-GHz band.
