Abstract

Techniques for detecting contraband are described, as are techniques for generating an image of living tissue. A location of interest relative to a target space is received, and a radar signal is transmitted in the direction of the location of interest. Portions of the radar signal are detected with multiple receiving structures. The detected portions are processed to generate information corresponding to dielectric or loss properties, the properties corresponding to particular positions within the target space. A determination is made as to whether contraband is present in the target space based on the determined properties.
