A Study to Evaluate Digital Acoustic Links for Sonobuoy Applications.

Abstract

A study was performed to assess the applicability of digital acoustic-links for telemetry of data between sonobuoy modules. Specifically, operational range, power required, transmission frequency, and modulation format were considered. The primary conclusion obtained is that a low power digital acoustic link is feasible for transmission rates up to a few kilobits per second and ranges to several kilometers. However, to achieve this performance in a fading acoustic environment, diversity, either spatial or frequency, is required.
