Abstract

Beginning in 1977, Fairchild Weston Systems developed an electro-optical reconnaissance camera for the Mission Avionics Division, Avionics laboratory at WPAFB, Ohio. The goal of the Long Range Electro-Optical Reconnaissance System program was to penetrate heavy haze conditions while preserving requirements of coverage and resolution needed to perform reconnaissance tasks. Design constraints included worldwide operational capability, high resolution, high sensitivity and large area coverage. It was proven feasible to achieve these goals through the use of hybrid analog and digital processing. Haze removal, local area background subtraction, data compression and image reconstruction were demonstrated. This paper discusses mission requirements, the design, and presents some results of this thirty-six month advanced development effort.
