A simplified approach to solving finite rough surface scattering problems.
In this paper a simplified approach is described for the computation of scattering from finite length rough surfaces. In an earlier paper [Fawcett, J. Acoust. Soc. 118, 1348-1357 (2005)], it was described how to solve such problems by considering a scattering chamber and using the method of wavefield superposition to satisfy the various boundary and continuity conditions. In this paper, a form of the field in the interior of the scattering chamber is assumed and the solution to the scattering problem is reduced to solving a system of equations just along the rough surface. The solution to this system of equations can then be used to compute the scattered or total fields anywhere in the half-space. The results of this approach are compared to those obtained by other methods.
