Abstract
A radiometric model has been developed for modeling the effects of self emission, reflection of downwelled radiance, atmospheric transmission and path radiance on the radiance reaching an airborne or satellite sensing system. The model, which incorporates LOWTRAN 6, includes angular emissivity effects and will account for either specular or diffuse reflectance from targets and backgrounds. The model has been refined to facilitate its use in generating primitive synthetic images to study LWIR phenomena. In particular, various types of sensor related noise have been included in the imaging process. Images are presented simulating the effects of target-to-background contrast as a function of view angle, range, emissivity variation, and atmospheric effects. The potential for use of LWIR models in sensor and algorithm development is discussed.
