Reverberation Modeling and Data Analysis in ASIAEX
Smith, Kevin B.
MetadataShow full item record
Shallow water acoustics and the performance of sonar systems in littoral environments are critical areas of interest to the US Navy. In response to this, the Office of Naval Research sponsored a series of acoustics experiments in the East and South China Seas, hereafter referred to as ASIAEx. One of the components of these experiments was a study of shallow water reverberation. The long-term goals of this study are to provide a better understanding of shallow water reverberation, its statistics, and the primary mechanisms that define its structure. By improving our understanding, the influence of reverberation on active systems may be reduced through smarter data processing.
