Abstract
This paper addresses the development of an Infrared Scene Simulator for Hardware-in-the-loop simulation of tactical IR air-to-air missile seekers. The simulator uses infrared target and background images produced by several technologies which are optically combined, collimated, and presented to the seeker under test. The system is configured for use on an optical bench but could also be hardened for flight simulator mounting. The high radiance target images of the air-to-air engagement scenarios are generated using high temperature blackbody sources and iris targets in the form of geometric figures with the size under servo control. The targets use an X-Y translation slide and dynamic attenuator to simulate movement within the field of view, range closure and the attenuation effects of the atmosphere. These targets are used to generate the aircraft tailpipe and flare decoy images required by the simulation. The high radiance targets are combined with the image from a Multiple Dynamic Simulator-Infrared Emitter Array which produces the engine plume, aircraft fuselage and background image. The three targets are combined using two beamsplitters and the composite image is collimated and relayed to the seeker under test. A workstation-based computational system generates the array image for display in real time.
