Backscattering from a Gaussiandistributed perfectly conducting rough surface
Abstract
The original intent of the reported investigation was to find a solution to the composite surface scattering problem which provided for a continuous transition between the nearspecular physical optics and wideangle tilted plane Bragg solutions. The employed approach is based on analytical techniques rather than physical considerations. The analysis employs a perturbation technique developed by Burrows (1967, 1968, 1973), which because of its simplicity, is the key to the entire solution. The analysis is restricted to the case of backscattering from a perfectly conducting surface. General expressions are presented for the scattering from a Gaussian perfectly conducting surface characterized by an anisotropic spectrum and possessing many scales of roughness. The accuracy of the result is dependent upon the largescale structure having large height excursions and small curvature.
