Array-Based Uses of Underwater Sound in Unknown Ocean Environments

The long term goals of this project are: i) to predict and understand the characteristics of active and passive time reversing array (TRA) performance in shallow ocean waters, ii) to deduce the effectiveness of using a TRA for underwater communication and for surveillance of the acoustic characteristics of known or unknown environments, and iii) to determine how to exploit the generic propagation characteristics of underwater sound channels in order to enhance the performance of active and passive sonar systems in unknown environments.
