Abstract

The scalar and vector problems of diffraction of a plane wave by a rough body of revolution are considered. The problems are solved using a modified discrete source method. The results of calculating the scattering patterns for the case of deterministic irregularities of a body’s boundary are compared with the results of the method of extended boundary conditions. The effect of the degree of roughness of the boundary on the scattering pattern is studied, and diffraction by various rough multifoils of revolution, as well as by an uneven superellipsoid, is considered. The effect of small perturbations of the scatterer’s boundary on the geometry of the set of singularities of the analytic continuation of the diffracted field is discovered.
