In the following paper, a new concept for increasing the aiport security is proposed. As a part of this innovative system, a W-band person scanner with a circular aperture for 360° scans has been built up. The usage of the Synthetic Aperture Radar (SAR) principle allows the detection of concealed objects with a resolution of 3mm in azimuth and 3 cm in range direction.
