Abstract
The field of the invention is that of devices for detecting non-metallic objects concealed on human subjects. These devices are more particularly dedicated to the surveillance and protection of reserved access areas, such as airport areas. The device according to the invention comprises a portable detector comprising a transmitter and a receiver of microwave frequency signals disposed in an enclosure of chaotic geometry including a plurality of measurement holes. The microwave frequency signal measured by this detector depends on the nature of the objects disposed under the holes. A processing device linked to this detector is used to correlate the measured signals with prerecorded signals. When the correlation exceeds a certain threshold corresponding to the presence of suspect objects, an alarm is generated.
