Four Hydrophone Array for Acoustic Three-Dimensional Location

reportActive / Technical Report | Accession Number: AD0732042 | Open PDF

Abstract:

The report describes a non-rigid, floating, four-hydrophone array that can give accurate three-dimensional locations for certain underwater sound sources, particularly for those that are close. For more distant sounds, the array can indicate good directions bearings but range is liable to be uncertain. A system for concurrent calibration permits periodic reassessment of hydrophone positions.
