ABSTRACT:
A portal for security screening of transport passengers includes a THz trans-receiver. In one example of the portal, the trans-receiver includes a small-spot, reflective scanning arrangement including a single detector in a heterodyne receiver configuration. In another example, the trans-receiver includes a large-beam reflective scanning arrangement with the trans-receiver in a synthetic aperture radar (SAR) configuration.
