DIRECT SOLUTION OF THE INVERSE PROBLEM FOR ROUGH-SURFACE SCATTERING AT GRAZING-INCIDENCE

The paper considers the inverse scattering problem for a scalar wavefield incident at grazing angles on a one-dimensional rough surface. The problem is formulated first as a pair of coupled integral equations in two unknown functions, knowledge of which immediately yields the surface. A method is described for the direct approximate solution of this system. Preliminary results are presented in groups of complicated rough surfaces which are closely recaptured in all details except for scale.
