1. A method of sensing characteristics of an object, the method comprising:
- transmitting a stepped-frequency radar through an object;
detecting, with multiple receiving structures, deflected portions of the radar signal;
processing the detected portions to generate processed data including information associated with amplitudes and phases of the deflected portions, and with the locations of the receiving structures at which the deflected portions were detected; and
analyzing the processed data to determine information corresponding to dielectric properties of particular positions within the object.

Abstract
Sensing characteristics of an object includes transmitting a stepped-frequency radar through an object and detecting, with multiple receiving structures, deflected portions of the radar signal. The detected portions are processed to generate processed data including information associated with amplitudes and phases of the deflected portions, and with the locations of the receiving structures at which the deflected portions were detected. The processed data is analyzed to determine information corresponding to dielectric properties particular positions within the object.
