Paper Abstract

A computer based thermal scene simulation was developed for generating synthetic images to facilitate the design and test of missile born Electro-Optical (EO) seeker systems. A scene is composed of objects and a background selected from the available data base files. Objects are modeled by combining small planar facets to cover their three dimensional surface. Each facet is associated in the data base with the thermal and optical properties of the surface being modeled. The objects may be stationary or mobile. The background is modeled on the interior surface of a pyramid defining the extent of the scene, with the floor of the pyramid representing the earth surface and the sides of the pyramid representing above horizon. The pyramid surface is then divided into triangular facets. Each facet is assigned a uniform texture selected from the database of background materials. The simulation is designed to be used with missile 6 degree of freedom (6DOF) simulations, and generates images as seen by the seeker based on the instantaneous seeker line of sight, seeker position, seeker orientation, object orientations and positions, and background.
