Abstract

The spatial correlation in the backscattered field for waves incident normally on a random boundary is derived using Kirchhoff-Helmholtz scattering theory in which the effects of both boundary heights and slopes are included. The acoustically rough case is considered and it is shown that the scattering process may be interpreted in terms of a deep, random phase screen; the influence of the boundary slopes is interpreted as diffraction at the screen. For a directive source, it is shown that the spatial correlation distance of the field is determined by the correlation of the source shading for a wide variety of boundary conditions; limited experimental data supports this result. For an omnidirectional source, the spatial correlation coefficient is 2J1 (kg)/kg.
