Passive millimeter wave imaging growing fast by Yvonne Carts-Powell The area of passive millimeter wave imaging is still in development, but both commercial and military applications abound for the technology. A conference on passive millimeter wave imaging technologies will be held at Aerosense in March. "Most of the world leaders and renown people [in this area] will be there," says Chair Roger Smith of the Air Force Wright Laboratory (Eglin AFB, Florida). Desire and past Active radar at longer wavelengths and infrared (and optical) systems at shorter wavelengths are more mature technologies, but passive millimeter wave sensing could add some...
