Scenario Based Radio Simulator and Analysis Tool

Toyon proposes to develop a scenario-based radio simulator and analysis tool which can be used to simulate, analyze, and test the next generation of mobile, multi-protocol tactical systems. The tool, based upon Toyons Geospatial Analysis Planning Support (GAPS) Toolbox, provides a geographic information system (GIS) framework complete with an intuitive graphical user interface, detailed 3-D environment models (terrain, foliage, buildings, and weather), dynamic vehicles, rapid line-of-sight algorithms, widely used communication models, and real-time network analysis. The simulator computes and outputs parameters for each RF channel (including multi-path values) as vehicles/radios move about the scenario, automatically selecting the most appropriate models for path loss, delay, Doppler shift, multipath, and fading. The simulator interfaces directly to a channel impairment emulator, and together (simulator and emulator) they provide the capability to evaluate wireless systems operating within a realistic scenario. In Phase I, we developed the prototype tool, built a relevant operational scenario, and demonstrated the real-time visualization of time varying RF link characteristics. In Phase II, we will complete and deliver the simulator, along with supporting datasets, external applications, and model libraries. We will advance the underlying algorithms and models, interface and test to multiple channel emulators, and demonstrate the real-time channel characterization capability.
