1. A microwave imaging system, comprising:
- an antenna array including a plurality of antenna elements, each capable of being programmed with a respective first transmit direction coefficient to direct microwave illumination from a first focal point on said array toward a target on an object and a respective first receive direction coefficient to receive reflected microwave illumination from said target to capture a first microwave image of said object and each capable of being programmed with a respective second transmit direction coefficient to direct microwave illumination from a second focal point on said array toward said target and a respective second receive direction coefficient to receive reflected microwave illumination from said target to capture a second microwave image of said object; and
a processor operable to measure a respective intensity of said reflected microwave illumination for said first microwave image and said second microwave image to determine respective values of respective voxels within said first and second microwave images of said object, and wherein said processor is further operable to construct a stereoscopic microwave image of said object from said first and second microwave images.

Abstract
A microwave imaging system for constructing a stereoscopic microwave image of an object includes an antenna array with a plurality of programmable antenna elements and a processor. Each of the antenna elements is capable of being programmed with a respective first direction coefficient to capture a first microwave image of the object from a first focal point on the array. In addition, each of the antenna elements is capable of being programmed with a respective second direction coefficient to capture a second microwave image of the object from a second focal point on the array. The processor constructs the stereoscopic microwave image from the first and second microwave images.
