Luggage Scanning at 80 GHz for Harbor Environments

In this paper, we present the results of a security-related case study using an 80 GHz millimeter-wave scanner with a large bandwidth of 25.6 GHz. The scanning system is based on a single transceiver that can be translated in two dimensions. By means of synthetic aperture radar (SAR) signal processing it is possible to calculate 3D-images for the detection of concealed objects. Imaging results will be present here for a knife and a revolver within a leather briefcase.
