Description
A daily study spanning a month of the shallow water acoustic channel was conducted to
estimate the environmental influence on performance of an underwater acoustic communications
system. An automated acoustic modem transmitted phase-coherent modulated sequences of
identical data with 186 dB re IpPa source level, at coded rates from 4000 to 16000 bits/s with
4 or 8 kHz symbol bandwidth, three times daily for a month. A 64 channel Mills-Cross receiver
array was used with horizontal and vertical beams each containing 32 and 33 elements
respectively, spaced 0.03 meters apart, with a sampling frequency of 72 kHz. Source and
receiver were deployed at depths of 20 meters respectively, with a 720 meter separation range.
Environmental measurements of wind velocity and direction, surface wave activity, current and
sound velocity profiles, and tidal measurements were performed. Results demonstrate reliable
achievement of high data-rate shallow water acoustic communications using phase-coherent
modulation techniques.
