Paper Abstract

The methodology for calculating aircraft infrared radiation is developed by expressing the signature in its component parts and then modeling each in terms of a few parameters. The basic signature components are: exhaust plume molecular emissions, airframe thermal emissions, various exposed engine hot parts, and scattered ambient radiation (e.g., earth-shine, sunshine and skyshine). When calculating sensor irradiances for systems studies, the close relationship between the aircraft signature and environmental conditions must be considered. This is illustrated with scene contrast signature calculations for several different observer viewing angles and background types.
