High Fidelity Front End Simulation for Complex Physics-Based Processing Systems Navy SBIR FY2005.1 Sol No.: Navy SBIR FY2005.1 Topic No.: N05-059 Topic Title: High Fidelity Front End Simulation for Complex Physics-Based Processing Systems Proposal No.: N051-059-0318 Firm: Sedna Digital Solutions, LLC 11350 Random Hills Road, Suite 800 Fairfax, Virginia 22030 Contact: Michael Beasley Phone: (703) 361-8333 Web Site: www.sednadigital.com Abstract: A high fidelity front end simulation system is proposed using proven and planned technology to minimize development risk and cost. The All World Environment Simulation (AWESIM) technology is used to provide high fidelity simulation. AWESIM technology is proven, modular and scalable. By coupling AWESIM with other planned products, the Sonar Trainer Interface Unit (STIU) and Sedna's Common Processing, we propose to address three major problem areas in the production cycle of tactical systems; system certification issues endemic with the use of low fidelity simulators, algorithm development support for the Advanced Processing Builds (APBs), and new sensor evaluation. For system certification issues, we describe a test configuration using AWESIM, the STIU, and the additional processing required to fully take advantage of the AWESIM's high fidelity engine. We also describe how to leverage assets at multiple sites while not encroaching on the integrity of natural sub-system interfaces. For APB development support, we show how using Sedna's Common Processing with AWESIM provides a supplement to recorded data. Sedna's Common Processing is designed from the ground up with flexibility, a must-have for APB developers. Finally, we show how to combine AWESIM and the Common Processing to support new sensor evaluation. Benefits: Commercial projects requiring high fidelity simulators for sensor based systems will directly benefit from this technology. For example, commercial development of new acoustic sensors would benefit from the concepts proposed in this SBIR. Typical new sensor development requires real world testing on a platform in an actual acoustic environment. This type of test can be very expensive and cost prohibitive to the developer. The approach defined in this proposal would allow the sensor developers to perform testing in a controlled lab environment at a much lower cost. This would also allow the developers to debug sensor system issues earlier in the development cycle also resulting in a cost reduction. Return
