Imaging electro-optical system simulations require high resolution digital terrain databases to support the image inputs into the simulation. These systems frequently employ spectral processing of the input data as a part of their operation. Generation of spectral signature data is critical to accurate simulations of these systems. This paper describes a prototype effort to generate background signatures which account for the spectral variations in the illumination sources and the background optical properties. These spectral signature data are subsequently employed in the rendering of high fidelity scenes to support the simulation.
