System and method for security inspection using microwave imaging

A security inspection system (10) uses microwave radiation to image targets (420) on a human subject (30) or other item. The system includes an array of antenna elements (200) that are programmable with a respective phase delay to direct a beam of microwave illumination toward a target (420) on the...

Zusammenfassung:	A security inspection system (10) uses microwave radiation to image targets (420) on a human subject (30) or other item. The system includes an array of antenna elements (200) that are programmable with a respective phase delay to direct a beam of microwave illumination toward a target (420) on the human subject (30) or item. The antenna elements (200) are further capable of receiving reflected microwave illumination reflected from the target (420). A processor (100) is operable to measure an intensity of the reflected microwave illumination to determine a value of a pixel within an image of the human subject (30) or item. Multiple beams can be directed towards the human subject or item to obtain corresponding pixel values for use by the processor (100) in constructing the image.
