<title>DIS IR simulation models for fidelity, signature texture, and atmosphere sensor effects</title>

Abstract

Distributed interactive simulation (DIS) or SIMNET has become the primary environment for force-on-force training, but realistic high-resolution IR effects for DIS have been lacking. Toward that end, the Night Vision and Electronic Sensors Directorate is currently developing an optimized synthetic infrared interactive simulation (OSIRIS) which incorporates real-time atmospheric and sensor effects into a high-resolution synthetic thermal scene for ground and air applications. OSIRIS is based on first-principles models designed to enhance the realism of IR simulations, and includes an MRT-based fidelity model, and IR background-signature texture model, and a dedicated real-time sensor simulator based on FLIR92 MTF and noise modeling.
