Abstract

Variable Resolution Modeling is a collection of techniques designed to make a higher fidelity model interoperate dynamically with a lower fidelity level model. We illustrate an example of this technique by using a high fidelity Space Based Radar (SBR) sensor model interoperating in real-time with Extended Air Defense Simulation (EADSIM), a US Government standard mission level simulation. The SBR performance is captured in a Commercial-Off-the-Shelf (COTS) database during parametric runs, and analyzed using standard Matlab tools. The functional performance is abstracted using a variety of a multidimensional table look-up methods and neural network representations. Finally, a real-time interactive module has been created to communicate with EADSIM using Distributed Interactive Simulation (DIS) protocols to provide a high fidelity SBR performance model. Although specialized software was created, called DeLoRes, this technique heavily exploits the availability and applicability of several COTS tools and the standardization of inter-application communications. Additionally, this technique leverages existing capabilities in EADSIM.
