An active personal screening method at 360 GHz based on an FMCW-MIMO approach - A TeraSCREEN subsystem

The present paper focuses on the development process of a novel, active terahertz scanner at 360 GHz. This system will be used at airports for the detection of threats, hidden on the screened passengers body. It is based on an electromechanical steered FMCW-MIMO approach with 16 transmitters and 16 receivers, which is able to screen moving passengers with a video frame rate of 4 Hz at a stand-off distance of 5 m. The described active subsystem is part of a multisensory approach. Keywords: Personal screening, body scanner, very high frequency, FMCW, MIMO, active scanner, terahertz, TeraSCREEN.
