Short Distance Related Security Millimeter-Wave Imaging Systems

Homeland security as a current issue brought up many questions about nowadays state of the art security relevant technologies both for civilian and military applications. Our motivation is related to security applications for airport environments especially in terms of people screening and object detection beneath the clothing. When developing a system for this environment one has not only to take into account good image quality but also issues like available space and financial resources of the airport’s operator. In this paper we report about general solutions to this task and about our approach in the millimeterwave region specifically.
