Raytheon Missile Systems (RMS) conducts ongoing research into an extensible general-purpose missile simulation framework. Recent research has focused on the development of a generic seeker simulation framework to support effective seeker design and verification. This paper presents advances in the techniques used to integrate the scene generation capability into <i>genSim</i>, the extensible off-the-shelf missile simulation implementation developed at Raytheon Missile Systems. The most recent field of inquiry is the robust scene generation of synthetic infrared signatures (including both land-vehicular and maritime targets) and is an element of the network-centric Future Combat Systems (FCS) program. In response to our DoD customer's transition to a capabilities-based technology acquisition and development approach, a discussion of scene generation simulation integration is of interest because of the increased use of simulation in the validation of weapon system performance.
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.
