Review of Models of Beam-Noise Statistics

Abstract

For system performance estimation and the interpretation of measured data, there is a need to predict and simulate the statistical properties of the response of a horizontally-directive acoustic array to ambient noise. In current use in the Navy there are a number of such 'beam-noise' models which predict the properties of noise caused by the dominant, prevailing source at low frequencies: surface shipping. The objective of this study is to review these models in some detail and then to recommend, for specific applications, approaches which utilize the best features of each model.
