Mid-Frequency Ambient Noise Spatial Structure and Implications for Passive Signal Processing

摘要

The purpose of this 3.5-year project was to investigate experimentally the time-evolving spatial distribution of ocean ambient noise and signals in the 1-10 kHz frequency band using multi-element hydrophone arrays with very high resolution in the vertical direction. These measurements were used to guide the development of algorithms for passive signal/array processing that were effective in detection, localization, and tracking of quiet submerged sources of interest.
