Abstract: This presentation will review progress that has been made over the last fifteen years in the design and use of millimeter-wave (MMW) imagers. This technology has been pursued because of its capability for imaging through clothing, fog, smoke, and dust with high enough spatial resolution to be useful. This makes it appropriate for such applications as concealed weapons detection, helicopter situational awareness in low-visibility, and surveillance. This type of imaging is distinct from radar in that the receivers do not usually perform coherent detection and ranging. Rather, imagery is collected in a manner similar to an infrared or visible camera and data is presented in an easy to interpret two-dimensional image. In this talk the device technologies, system architectures, and phenomenology associated with MMW imaging will be discussed. Also presented will be the outlook for future imaging systems that promise affordability in kilo-pixel camera systems..
Bio: David Wikner has been actively involved in MMW radar and imaging research for the past 18 years at the Army Research Laboratory. His work has focused on advanced imaging system architectures, device technology and phenomenology. He developed a Stokes-vector passive MMW imaging system that is used for studying the polarimetric signatures of materials and objects for Army applications. His current work pursues the development of affordable device technology for next generation MMW imagers.
