Paper Abstract

This paper addresses advances in techniques used to produce credible Infrared (IR) optical target images and point source intensities for effective simulation testing and validation. Integral to a credible simulation process is the ability to accurately generate and inject synthetic imagery into various simulation topologies for model verification, validation and accreditation. This research exploits improvements in computational power and refines the modeling algorithm in response to the demands for significantly increased detectivity requirements in target discrimination. The software architecture is Commercial-Off-The-Shelf (COTS)-based and results from judicious implementation of performance sensitivity analysis indicators of how the threat and background signatures vary as a function of changes in factor values. A novel approach to determine the minimal image set for a trajectory is presented, using the Intensity Variation Threshold (IVT). Several illustrative examples are presented to show how inherent limitations in the COTS software have been effectively mitigated for a cost-effective solution. This approach is well suited to provide enhanced target imagery and improved flexibility and control over threat geometry and thermal effects within an end-to-end simulation. A discussion of recent advances in modeling target and background synthetic imagery modeling is of increased interest in the military community because of the use of simulation for validation of weapon system performance.
