Abstract
© 1988 SPIE. All rights reserved. The Infrared signature of a vehicle is dependent on its surroundings in two ways. First, the vehicle image perceived in an IR scene is directly related to the thermal contrast between the vehicle and its physical environment. Second, the vehicle surface temperature is determined, in part, by the energy exchange at its boundaries which includes the continuous radiative heat exchange with its surroundings. A vegetation background model has recently been developed to support the vehicle signature model, PRISM. The model is a first principles approach to predicting vegetation temperatures based on boundary conditions established by the surface environmental input. This paper will discuss the background model in terms of thermal physical behavior, model assumptions, and the model itself. In addition, model validation will be presented that shows simulation results that fall into the maximum/minimum bounds established by diurnal thermal imagery data gathered in support of this activity.
