Improved Radio Frequency (RF) Modeling for Correlated Environment Communication System Simulators with Sensor Simulators

Echo Ridge proposes to develop real time RF modeling for a communications system simulator capable of accurately emulating the RF environments. The proposed simulator will increase the realism of the flight simulator by emulating the channel characteristics between intentional and unintentional RF devices including communications, sensing (i.e. radar), and navigation systems. The system will calculate these characteristics on-the-fly (OTF) as the pilot flies the simulator. A primary objective of the RF path simulation is to add as much realism as possible while minimizing latency so that the RF modeling simulation is correlated with the other flight simulator sensors and cockpit displays. This project will create a RF simulator ensuring that the RF signal-derived stimuli the pilot hears or sees in the cockpit displays matches and is synchronized with what he sees through the cockpit window, sees on his cockpit sensor displays from his other sensors, or feels through the motion simulator.
