Expansion of a 2-D Array for Acoustic Field Structure Research

Abstract

This research grant supports the fabrication and expansion of a hydrophone array for use in the collection of ambient noise and underwater acoustic propagation data. The work plan includes the purchase of 128 hydrophone elements that will be integrated into an existing system to provide capabilites to configure a single two-dimensional planar array totaling 512 elements or multiple 128-channel, high-resolution vertical arrays. The proposed work includes development and facrication of the necessary data acquistion systems to support acoustic data collection. The new program takes advantage of a previous design for hydrophones and data acquistion systems developed with previous DURIP support. The resulting system will be used to collect underwater acoustic data for exploring basic research questions related to ambient noise, acoustic propagation, advanced signal processing, geoacoustic inversion, and passive target detection.
