THE EFFECT OF BOUNDARIES ON THE SPATIAL CORRELATION OF NOISE FIELDS

Abstract

The effect of boundaries on the spatial correlation of noise fields is investigated. Two types of noise fields are considered; namely, a volume noise model and a surface noise model. The volume noise model consists of a field of plane waves, equally probable in all directions. This homogeneous- isotropic noise field is modified by the addition of a perfectly reflecting soft surface. The addition of the boundary results in a nonisotropic, nonhomogeneous wave field. Equations for the spatial correlation are obtained and curves are drawning the dependence of spatial correlation on the orientation of the point receivers and the distance from the soft surface. This analysis repeated for a hard bottom.
