Abstract

Under contract to Rome Lab, Grumman performed studies to determine the magnitude of aircraft infrared (IR) intensities in arctic environments. These studies were then used to establish the requirements of aircraft intensity component measurement facilities. This paper will investigate and assess environment-driven IR intensity components for use in planning future IR measurements under arctic environments. This assessment includes earthshine, solar reflections, solar heating, skyshine, atmospheric attenuation, and background/foreground radiance associated with arctic environments. Results from trade studies are presented, along with a summary of the IR intensities expected under arctic environments. The major findings of this study indicate that by controlling the IR intensity components driven by flight conditions and atmospheric attenuation, measurements of environment-driven IR intensity components need to be performed. This is particularly interesting under arctic environments where the environment-driven IR intensity components have an impact on the overall IR intensity of the airframe.
