Abstract
This 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.
Appendix: Programming and mathematics for computer analysis of the array
data are by Donna Ekstrand and Mary Hunt.
