The paper describes an infrared scene generator (IRSG) mounted on a Flight Motion Simulator (FMS) for hardware in the loop simulation of IR air to air missile seekers. The scene generator projects target, flare and background images, that are optically collimated to the seeker under test. The target and flare images are generated using high temperature (1200 degree(s)C) blackbody sources and controllable irises. A dynamic Variable Neutral Density Filter (VNDF) is used in the target and flare channels to simulate the range closure and attenuation effect of the atmosphere. The background channel consists of a back illuminated IR transparency located in front of an extended area blackbody. The target flare and background images are combined using two beam combiners. One of the beam combiners has two degrees of freedom to simulate the motion of the flare relative to the target within the field of view (FOV) of the IRSG.
