Abstract

Radar systems and methods for imaging concealed surfaces. A processor receives raw data from the radar and executes an image data generation. A display unit displays an image representing the concealed surface. The radar unit may be incorporated in a handheld scanner, a walkthough scanner, an underfoot scanner, an overhead scanner or the like. Dimensions of the scanning unit may be selected to enable a full body scan of a subject.
