Abstract

The inverse-scattering problem for a scalar wave field incident at grazing angles upon a one-dimensional moderately rough surface is considered. The problem is solved directly by treating the scattering integral as an integral equation in the unknown field derivative at the surface and coupling this to a simple equation relating the derivative to the surface itself. An algorithm is described for the solution of this system, and results in which complicated rough surfaces are accurately reconstructed are presented.
