Paper Abstract

Passive imaging technology has been recognized and reduced to practice for sensing targets in the battlefield environment for several decades. Most imaging is done at optical and infrared wavelengths which require favorable weather conditions. This paper describes what is on the horizon for a new imaging technology 'passive millimeter wave (PMMW) imaging' that can operate in all weather conditions. It will introduce the reader to the unique world of PMMW imaging by describing the technical approach underway at the Wright Laboratory Armament Directorate, Advanced Guidance Division, Eglin AFB, Florida. A PMMW analytical model has been developed and a data collection/phenomenology testbed is being built to validate this model. This will be a mobile test facility that will provide the needed ground truth for an Airborne PMMW Captive Flight Test program in the FY97/98 timeframe. The thrust of this analytical model is the treatment of theoretical equations that allow low altitude imaging in and out of the millimeter wave spectral 'window' frequencies. PMMW sensors at 35, 60 (non- window), and 95 GHz are being fabricated and will be collocated on the same platform to validate this model. This testbed will be the hardware used to begin a radiometric imaging program that will serve not only military needs for advanced munition sensor development, but commercial and academic endeavors as well.
