Radiation from a charged particle travelling parallel to a rough surface has been considered. The spectral-angular intensity is calculated in the weak scattering regime. It is shown that the main contribution to the radiation intensity is determined by the multiple scattering of polaritons induced by a charge on the surface. Multiple scattering effects lead to a strong frequency dependence of the radiation intensity. Possible applications in beam and surface diagnostics are discussed.
