Paper Abstract

The generation of high-fidelity simulated infrared imagery requires a unique combination of physical principles and computer image generation technology. At the Georgia Tech Research Institute infrared simulation software has been developed that couples three-dimensional geometric models with geographic databases, infrared radiance prediction models, and computer graphics techniques for image rendering to generate high-resolution synthetic infrared imagery. These features provide a large degree of flexibility to the simulation and allow it to be employed over a wide spectrum of applications. A discussion of a simulation methodology, a review of the GTVISIT scene simulation tool, and a discussion of several applications are given.
