Abstract

The infrared exitance of steel plates with several emissivities are modeled using PRISM 3.0 and LOWTRAN7 under sky backgrounds representative of Middle East desert conditions in the summer. LOWTRAN7 is used to calculate the downward thermal radiance of a desert haze atmosphere with multiple scattering. PRISM 3.0 incorporates the results from LOWTRAN7 into annular rings that represent the temperature gradiant of the sky dome and predicts the apparent temperature of the plates in the 8 to 14 micron band. This study is part of a preliminary look at the issue of passive low observable technology for application to ground vehicles and an illustration of state-of-the-art computer-based background modeling and thermal simulation.
