Because single systems have not often the desired reliability, the concept is based on the fusion of different sensors. Moreover, first measurements of a 94 GHz person scanner with circular synthetic aperture are presented showing the capability to detect metallic as well as nonmetallic objects without violating the personal privacy.enradarsynthetic aperture radar (SAR)securityimaging667004621Sensor fusion based security concept on airports with a rotating millimetre wave person scannerconference paper
