Mid-Frequency Environmental and Acoustic Studies from SW06, and Applications to Asian Littoral Waters

摘要

To develop a basis for the Navy to make decisions on what environmental parameters to measure, to what spatial and temporal scale they should be measured, and how to best select frequencies for sonar design. Emphasis is on the mid- to high-frequency range defined as frequencies nominally between 1 and 20 kHz, with the goal this year expanded to included vector properties of the forward propagating acoustic field. The primary objective this year was analyze measurements of pressure spatial coherence, and pressure-velocity coherence, from Shallow Water 06 (SW06) obtained by the PI in August 2006, and model these data based on measured environmental processes.
