(IAI) details an innovative approach for on-the-fly (OTF), physics-based radio frequency (RF)propagation modeling that appropriately interacts with complex synthetic natural environments (terrain, cultural features, atmosphere/weather) for more realistic communication systems and radar sensor simulations. Specifically, IAI proposes: 1) novel physics based, efficient simulations to accurately and rapidly predict channel conditions between arbitrary transmitter-receiver pairs as they move through the complex. The approach is based on deterministic ray tracing combined with statistical modeling and utilizes a common, material/property-attributed synthetic natural environments (terrain, atmosphere and ocean) like to those used for vis-sims (OTW, EO/IR, MWIR and radar sensors, allowing the effect of the environment to impact all simulations coherently. 2) Wideband hardware emulation of the simulated link characteristics. Hardware emulation allows for incorporation of hardware radios in the simulation, improving the fidelity. Benefits: Incorporating the non-idealities in comm.-sims will allow more accurate assessment of combat utility of communications networks, and support improved interoperability between naval and ground forces. Private sector applications include the gaming industry, and test routines for communications device manufacturers such as cell/wireless providers, etc Return
