A 2-D Array for Acoustic Field Structure Research
Abstract
Proposed is the fabrication of a 2-D array for use in the collection of mid-frequency (0.5-10 kHz)ambient noise and underwater aco"ustic propagation data. The array will facilitate fundamentaladvances in our use of ambient noise as a natural environmental probe source as well as ourcapitalizing on ambient noise spatial structure for target detection processing. The array also willfacilitate investigating basic research questions in the fluctuation characteristics of midfrequencysignal propagation and attenuation. The entire array will consist of 512 hydrophonesarranged in a 2-D distribution of elements (8 vertical staves of 64 elements each) enablingbeamforming (spatial filtering) in both the vertical and horizontal directions. An integratedautonomous data acquisition syst"em is included.
