Acoustic noise models

Abstract

The question of modeling the vertical directionality of ambient noise in the ocean is considered. The problem of converting from adescription in terms of directional density function to a description in terms of the cross-spectral density function between pairs of sensorsof arbitrary orientation and separation is examined in detail. Mathematical models which have been used previously are reviewed with special emphasis on spatial harmonic models following closely some material presented earlier.
