Remote detection and measurement of objects
First Claim
1. An apparatus comprising:
- a transmitter configured to transmit at least one of microwave and millimeter wave radiation varied over a range of frequencies;
a detector configured to receive radiation resulting from the transmitted radiation to enable production of a frequency-dependent detection signal; and
a controller configured to detect an object upon which the transmitted radiation is incident based at least on an oscillatory term in the detection signal indicative of a dimension of the object.

Abstract
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. A system and method for remote detection and/or identification of a metallic threat object using late time response (LTR) signals is also disclosed.
