Passive millimeter-wave imaging for airborne and security applications

Abstract

As a result of its relatively short wavelength coupled with relatively high penetration of such things as fog, bad weather and clothing, millimeter-wave imaging provides a powerful tool for both airborne and security type applications. By using a passive approach such as that implemented here, it is possible to image through bad weather or detect concealed weapons and articles all without generating any form of radiation that might either help an enemey or raise health concerns. In this paper we will show imagery from our second generation state-of-the-art unit and discuss the technology involved.
