Ocean Acoustic Propagation and Coherence Studies

Abstract

The long-term objective is to develop knowledge of factors controlling the mean and the variability of acoustic fields in the shallow ocean environment, in the frequency band 50 Hz to 3000 Hz. Propagation variability is an inescapable complicating factor for both active and passive sonar systems, and for underwater acoustic communications. Reliable predictions of temporal and spatial variability of received underwater sound can improve processing and handling of signals of interest, for example the remediation of signal degradation, the exploitation of intermittent sonic information, or the exploitation of favorable propagation conditions.
