Abstract
A rugged IR scene simulator (IRSS) is described which combines two, independently moving, dynamic IR targets and a third background source by means of a single beamsplitter. Each target may be separately controlled to produce pitch, yaw, and range closure motions under computer control. The entire system is designed for mounting on the inner axis of a high speed Target Motion Simulator gimbal system surrounding a three axis Missile Motion Simulator. Interchangeable optics for 1.5-5μm or 8-14μm may be employed or broadband 2.25-141μm optics can be used with some minor loss of resolution. Easy access to the two focal planes permits substitution of different servo controlled shaped targets or the use of dynamic pixel arrays interchangeably. Cooling of the internal optics permits operation with low background radiance from the system itself. Both the IRSS and the various target modules presently existing and planned are discussed.
