Ocean Ambient Noise Statistics for the Detection of Transients

Abstract

The report stems from the observation of data whose statistical parameters, such as the means and variances, mask essential information like transients or possibly target signal levels imbedded in background noise. Transient information in this report implies that a large displacement of a very small percentage of samples exists in the data. The report shows that this information contained within the means and variances of ocean ambient noise data can be removed by the manipulation of the differences of some of the higher order moments. Techniques in this analysis were specifically oriented to help solve detection problems currently faced by the Anti-Submarine Warfare community.
