Abstract
An infrared scene generator code has been developed for use in testing electro-optic systems. The scene generator combines sophisticated computer graphic techniques with first-principals background modeling. The code generates apparent radiance images of a scene composed of polygonal and/or quadric objects for a specified viewing geometry, spectral band, weather, time of day, location, season, and sensor field of view. Surfaces may be any one of 15 different materials and any surface can be given a texture to make the generated scene more realistic. The warming of surfaces caused by sunlight is also modeled. All parameters, including the effect of the intervening atmosphere, the weather, material type, material texture, and the system modulation transfer function, are contained in independent data bases. The use of data bases, combined with efficient programming, make the execution time short. This allows the user to quickly see the effects of different conditions on the scene of interest and how varying conditions will effect a sensor system.
