Using AUV's and Sources of Opportunity to Evaluate Acoustic Propagation
1998
Glegg, Stewart A
To develop a passive acoustic volume array for the AUV Ocean Explorer II which may be used to investigate different sources of sound in the coastal region. The system will be able to autonomously detect changes and variations in the near shore environment by measuring acoustic propagation from ambient noise and man-made sources. The system will also collect breaking waves noise directivity data to be correlated with turbulence measurements taken close to the sea surface. The objective of this research is to develop a fully functional payload for the AUV Ocean Explorer II to perform passive sonar measurements from a stationary platform. The system will be able to undertake missions which include multiple Landing/Measurement/Takeoff sequences, so that it can monitor ambient noise variations at many different locations. In a moored version the system will measure noise directivity over long periods of time to study the temporal variation of ambient noise in the coastal region. Finally, the payload will be used to track moving AUV's by measuring the directivity of modem signals emitted from the vehicles.
