Directional Autobuoy: Initial Engineering and Acoustic Results.

Abstract

The AUTOBUOY is a deep diving, self-contained, programmable data acquisition system. Three two-hydrophone systems have been built for the Navy and one of them has recently been modified to accept a long vertical array for the collection of low frequency (30 to 500 Hz) noise directionality data. The modified system, designated Directional AUTOBUOY, is designed to collect a total of 16 hr of data while hovering at as many as five different depths to 6,000 m on a single deployment. The completed system has been sea tested and the acoustic results have been analyzed using a computer algorithm designed for this purpose. Design deficiencies noted during the sea tests have been corrected, and plans for developing large horizontal arrays for this system are described. (Author)
