Simulation of scenarios for modern seekers involves the generation of multiple targets, electro-optical counter measures and textured backgrounds, all with realistic physical characteristics. True intensity, spectral distribution, real angular size and velocity are essential. The optical and radiometric design approach is based on imaging the seeker entrance pupil on different positions on a scene generation table. This paper presents some of the novel system characteristics. The optics, comprising mostly reflective surfaces and uncoated beam combiners, provides wide infrared and visible spectral range. The system is designed for high resolution over a large 10 degree field of view and is optimized for maximum intensity. Gimbaled mirror axes states are transformed into real world line of sight (LOS) motion. The whole scene may be tilted with respect to the seeker axis at large angles with derotation compensation. Targets, flares and thermal backgrounds are implemented using diversified types of thermal radiators, and their intensity and size closing effects are controlled by opto/electro-mechanical assemblies.
