Progress in the development of a cold background, flight motion simulator mounted, infrared scene projector for use in the AMRDEC Hardware-in-the-Loop facilities

摘要

This paper will present the progress on AMRDEC's development of a cold background, flight motion simulator (FMS) mountable, emitter array based projector for use in hardware-in-the-loop systems simulation. The goal for this development is the ability to simulate realistic low temperature backgrounds for windowed/domed seekers operating in tactical and exo-atmospheric simulations. The projector has been developed to operate at -10 degrees Celsius in order to reduce the apparent background temperature presented to the sensor under test. The projector system includes a low temperature operated Honeywell BRITE II emitter array, refractive optical system with zoom optics, integrated steerable point source and high-frequency jitter mirror contained within an FMS-mountable environmental chamber. This system provides a full-FOV cold background, two-dimensional dynamic IR scene projection, a high dynamic range independently steerable point source and combined optical path high frequency jitter control. The projector is designed to be compatible with operation on a 5 axis electric motor driven Carco flight motion simulator.
