ON THE MOVE MILLIMETER WAVE INTERROGATION SYSTEM WITH A HALLWAY OF MULTIPLE TRANSMITTERS AND RECEIVERS

摘要

In some aspects, the disclosure is directed methods and systems for screening an unconstrained subject. A plurality of transmitters may be spatially distributed on two sides along a path of movement of a subject Each of the transmitters may transmit, in sequence, radiation to be scattered from the subject. A plurality of sensors may be spatially distributed on the two sides and coherently configured with respect to the plurality of transmitters. The plurality of sensors may collect measurements of scattered radiation corresponding to the radiation transmitted by each of the plurality of transmitters. An imaging module may generate, based on the collected measurements, a two-dimensional or three-dimensional reconstruction estimate of body surface of the subject with one or more attached foreign objects

1. A method for screening an unconstrained subject, comprising:
(a) transmitting, in sequence by each of a plurality of transmitters spatially distributed on two sides along a path of movement of a subject, radiation to be scattered from the subject; (b) collecting, by a plurality of sensors spatially distributed on the two sides and coherently configured with respect to the plurality of transmitters, measurements of scattered radiation corresponding to the radiation transmitted by each of the plurality of transmitters; and (c) generating, based on the collected measurements, a two-dimensional or three-dimensional reconstruction estimate of body surface of the subject with one or more attached foreign objects.
