Extracting Coherent Information from Noise Based Correlation Processing

Abstract : The goal of this research is to establish methodologies to utilize ambient noise in the ocean and to determine what scenarios are best suited for applying these methods. Because noise-based correlation processing is based on equilibrium related stationary statistics, the ocean does not really provide a cooperating scenario for such processing. The objectives of this research is to develop array and signal processing that overcome the effects of the fluctuating ocean by essentially developing techniques that speed up the processing to time scales shorter than those of ocean fluctuations. The approach has been a combination of experiment/data analysis and the development of appropriate signal processing methods.
