High Fidelity Front End Simulation for Complex Physics-Based Processing Systems

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.
