摘要

The long-term objective is to develop a reliable ambient-noise inversiontechnique for obtaining the geo-acoustic parameters, including the stratification, of the sea bed from measurements of the broadband vertical coherence of the noise in shallow water. The method would be implemented in a free-floating instrument, self navigated with GPS, and consisting of a pair of vertically aligned hydrophones, to provide a cost-effective sensor system for collecting the required noise data over extensive areas of shallow water. The resultant bottom information would provide essential input to navy propagation loss models.
