Spectral Correlation Properties of Time Series Due To An Acoustic Source Moving Through An Oceanic Waveguide.
Abstract
The time series representing the acoustic energy received at two sensors due to a source moving through an oceanic waveguide can exhibit strong spectral correlation between different frequencies. This correlation can be exploited to enhance passive detection of moving targets particularly in shallow water and near field environments. The structure of this spectral correlation is derived in this document. It is also shown that established techniques can estimate the spectral correlation from time series. This algorithm is assessed on real underwater acoustic data. Excellent agreement is observed with theory.
