Abstract:

The overall long-term goal for this project is to develop engineering tools that are useful to the Navy as it operates in uncertain, partially known, or unknown ocean environments. During the last year, this project has focused on further determining the utility of a time-reversal-based technique for blind deconvolution of recorded sounds broadcast by a remote source with emphasis on determining if and how the results might be used for classification, localization, tracking, andor identification of remote sources in poorly known or unknown multipath waveguide environments. The long term goals of this project are i to determine the effectiveness of artificial time reversal ATR for the purposes of blind deconvolution in noisy unknown ocean sound channels, ii to effectively apply ATR to marine mammal sounds recorded in the ocean with vertical andor horizontal arrays, and iii to utilize the ATR-estimated signals and ocean-sound-channel impulse responses to identify, localize, andor track individual marine mammals or other sound sources of interest.
