Abstract

This talk will address propagation modeling of underwater acoustic channels for underater vehicle-to-vehicle communications. Many scientific, defense, and safety endeavors require communications between untethered submerged devices and/or vehicles. Examples include sensor networks for seismic monitoring, analysis of resource deposits, oceanographic and environmental studies, tactical surveillance, etc., as well as communications between Unmanned or Autonomous Underwater Vehicles (UUVs, AUVs) for deep-water construction, repairs, scientific or resource exploration, defense applications, etc. Dr. Zajic will present the first wideband statistical channel model for acoustic underwater communications. The model was verified against measured data and very close agreement between measured and simulated data was found. She will also present the first algorithm that estimates both velocities between autonomous underwater vehicles in underwater acoustic communications.
