System and method for standoff microwave imaging
First Claim
1. A microwave imaging system for performing standoff microwave imaging, comprising:
- an antenna array including a plurality of antenna elements, each capable of being programmed with a respective direction coefficient to direct microwave illumination toward a target within a volume that includes a standoff region, said antenna elements being further capable of being programmed with a respective additional direction coefficient to receive reflected microwave illumination reflected from said target; and
a processor operable to measure an intensity of said reflected microwave illumination to determine a value of a voxel within a microwave image of said volume, and wherein said processor is further operable to construct said microwave image with a resolution sufficient to identify objects within said standoff region.

Abstract
A microwave imaging system for performing standoff microwave imaging includes an antenna array with a plurality of antenna elements, each capable of being programmed with a respective direction coefficient to direct microwave illumination toward a target within a volume that includes a standoff region, and each capable of being programmed with a respective additional direction coefficient to receive reflected microwave illumination reflected from the target. A processor measures an intensity of the reflected microwave illumination to determine a value of a voxel within a microwave image of the volume. The processor constructs the microwave image with a resolution sufficient to identify objects within the standoff region.
