Development of an IR stimulator concept for testing IR missile warning systems

摘要

Abstract: Missile warning systems (MWS) present unique problems for hardware-in-the-loop testing compared to other sensors found on modern day military aircraft and ground vehicles. End-to- end testing of an IR MWS like the AN/AAR-44 and other IR MWS requires a scene projector or stimulator capable of large intensity dynamic range, moderate temporal response, and a very large field of regard. These requirements dictate a different type of stimulator than is normally used with more conventional IR imaging systems using IR focal plane arrays and relatively narrow fields of view on the order of 10 - 30 degrees. This paper describes an initial design approach for development of an IR stimulator that satisfies the requirements for hardware and software testing of the AN/AAR-44 and other IR MWS equipment.!0
