Patent number: 11422252Abstract: Provided are methods of using electromagnetic waves for detecting metal and/or dielectric objects. Methods include directing microwave and/or mm wave radiation in a predetermined direction using a transmission apparatus, including a transmission element; receiving radiation from an entity resulting from the transmitted radiation using a detection apparatus; and generating one or more detection signals in the frequency domain using the detection apparatus. Methods may include operating a controller, wherein operating the controller includes causing the transmitted radiation to be swept over a predetermined range of frequencies, performing a transform operation on the detection signal(s) to generate one or more transformed signals in the time domain, and determining, from one or more features of the transformed signal, one or more dimensions of a metallic or dielectric object upon which the transmitted radiation is incident.Type: GrantFiled: July 1, 2019Date of Patent: August 23, 2022Assignee: RADIO PHYSICS SOLUTIONS LTD.Inventors: Nicholas Bowring, David Andrews, Nacer Ddine Rezgui, Stuart Harmer
