Abstract:

The performance of electro-optical weapon systems operating the visible and near-infrared IR spectra depend on the illumination of the target and background. Scene shadows can decrease the illumination level of the target scene and alter the contrast characteristics between the target and background. Shadows are also an important source of clutter in a target scene. The primary objective of the first year of this Phase II SBIR is to 1 develop the partly cloudy shadowing model, 2 deliver the updated TARGAC software for the PC that implements the partly cloudy shadowing model, 3 determine the relationships between target acquisition, small-scale features, shadows, and clutter, and 4 develop a design approach for the incorporation into TARGAC of the temporal and spatial characteristics of clutter.
