Paper Abstract

While THz and mm-wave imaging systems provide an interesting avenue for stand-off detection of concealed weapons and other threats without the need for ionizing radiation, there are many physical and technical obstacles which still prevent these systems from becoming commercially practical. This paper introduces the major issues for active and passive imaging including background masking, specular responses, and thermal equalization. Secondly, the paper discusses the prospects of radar imaging, and tradeoffs between system parameters such as transmit power, receiver sensitivity and phase noise, and how these parameters affect corresponding physical behavior including aperture size, resolution, penetration, and stand-off distance.
