On-the-move millimeter wave imaging system using multiple transmitters and receivers

A novel layout for an imaging system able to create real time radar images for personnel security screening is presented. The system uses multiple mm-wave transmitters and receivers placed along a hallway in a multistatic configuration. The layout consists of two flat panels of receivers placed on opposite walls. Transmitters are located around the hallway to provide multiple illumination angles. The main novelty is the fact of whole body imaging taking advantage of the person's movement along the hallway to increase the number of observation angles. The imaging is performed as the person being screened continuously moves through the hallway, then combining the recovered image for every position similarly to the different frames of a video. 3D simulation results showing the feasibility of the proposed system are presented.
