Research Topics


As cost becomes and increasingly important factor in the development and testing of IR seekers, the need for accurate hardware-in-the-loop (HWIL) simulations is critical. Recent technological advances and innovative applications of established technologies are beginning to allow development, from commercial-off-the-shelf (COTs) hardware and software, of cost effective replacements for expensive and complex dedicated scene generation hardware. In Phase I of this effort a Virtual Reality Scene Generator (VRSG) built around COTS hardware and software was designed as a replacement for existing expensive IR Scene Generators. The goal of this Phase II effort is to successfully integrate the VRSG into a HWIL IR Seeker testing environment. Efforts will be made to advance the current VRSG by adding atmospheric conditions, counter-measure modeling, and real-time IR predictive codes. Verification and validation testing will be performed to assure the accuracy of the VRSG design and implementation. Investigations will also be performed to determine the feasibility of transitioning the technologies of this research into a commercially viable product. To increase the potential for commercialization, both Distributed Interactive Simulation and High Level Architecture protocols will be added to the scene generator. These protocols will allow the VRSG to participate in standard networked simulation testing and training. Potential military products of VRSG technology include various man-in-the-loop training simulations and hardware-in-the-loop testing tools. Using the VRSG training can be performed over a wide range of scenarios including adverse weather conditions. Commercial applications include nighttime training for law enforcement and enhanced vision IR sensor simulation for aircraft and ground vehicles.
