Environmental Acoustics and Intensity Vector Acoustics with Emphasis on Shallow Water Effects and the Sea Surface
Abstract
The long-term goal is to understand and predict key properties of the signal intensity vector field in forward propagation with emphasis on mid-frequency, shallow water propagation. Because of enabling technologies involving MEMS and bio-inspired transduction, tomorrow s navy will depend on and utilize acoustic vector field properties (velocity, acceleration, intensity) much more than today s. Advancement in Navy relevant capabilities will be in part realized through a better understanding of the environmental and acquisition geometry dependence (source depth, range, etc.) of the vector field in a shallow water environment. The primary technical objective this year was analyze was to (1) procure a VHS-100 vector sensor from China and test it in a controlled setting, (2) complete analysis on a new approach to obtain geoacoustic properties from vector quantities using data from Shallow Water 06 (SW06) experiment off the coast of New Jersey (2006) , and (3) complete a study on the effect of directional waves (from SW06.)
