Abstract

An image based comparison of modeled IR cameras in the medium- wave (MW) and longwave (LW) bands is done using the TARDEC thermal image model (TTIM) and LOWTRAN7. A state-of-the-art staring focal plane array (FPA), a common module scanning FLIR, and a scanning dual-band sensor are modeled. The simulations using TTIM demonstrate the imaging performance of the cameras as well as the degradation caused by the atmosphere in the two bands. Atmospheric degradation to the image is simulated in rain and fog in northern hemisphere environments.
