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.
