The article is dedicated to the mathematical modeling of the acoustic field, which is scattered by the homogeneous isotropic circular cylinder of finite length with the continuously inhomogeneous elastic coating. The density and elastic moduli of the coating material are described by continuous functions of the radial coordinate. The primary perturbation field is a plane harmonic sound wave obliquely incident on the body. The results of calculations of the angular and frequency characteristics of the scattered acoustic field in the far zone are presented.
Keywords: scattering, sound waves, finite elastic cylinder, inhomogeneous elastic coating.
