140 GHz Imaging Technology

"We are proposing a study to develop an optimum system architecture for an active and passive millimeter wave imaging system at 140GHz. Recent advances in III-V material such as InP enabled manufacturable, low cost, electronics for systems operating at140GHz. We intend to focus the energy from a scene through a lens to a 20X20 Focal Plane Array that is comprised of stable radiometers with an element spacing of 2.1mm. Operation in this frequency range providedThe proposed system has direct application toall weather landing systems for both day and night operation. There is a need for a low cost all weather landing systems for the commercial aircraft marketplace. The higher resolution at 140GHz also has the potential for applications for navigationsystems, targeting systems, weapons detection, and battle damage assessment. In certain situations, the system could be used for through the wall imaging, weapons detection, as well as fire location."
