Abstract: Apparatus and a method for scanning personnel for the purpose of detecting and identifying certain categories of materials/objects. The invention utilizes stacked-circuit-board tiled assemblies, including one circuit board which carries an array of transmission/reception scanning microwave elements, which elements, during a scanning operation are shifted toward and away successively from a person being scanned. This motion is carried out in a manner enabling detection of peak valley (high and low) values of standing wave reflections, if any, which exist between one of these elements and a region of a person being scanned by the invention. These peak and valley values can be employed, with respect to the magnitude difference between them, to enable “found material/objects” identification.

Abstract: A system and method for the dielectric scanning of a human subject to detect anomalies relative to expected normal physiology as an indication, among other things, of the possible presence of a weapon, contraband, or of a confirmed difference in personal identity. Persons expeditiously can enter a double-open-sided, ninety-degree counter-rotative scanning zone in the system, alternating from two orthogonally positional entry lines. Scanning occurs in two orthogonal phases of non-relative-motion interrogative microwave illumination to detect sequential, opposite-side-quadrant, dielectric physiologic anatomical signatures which are assessed by computer comparing them to pre-established physiologic-signature tables. Persons entering the scanning zone, leave along a quadrature-related exit path.
