A technique is presented for solving the problem of scattering by a three-dimensional body of revolution using a partial differential equation (PDE) technique, employed in conjunction with radiation boundary condition applied in the Fresnel region of the scatterer. The radiation boundary condition, which is used to truncate the PDE mesh, is based upon an asymptotic expansion derived by Wilcox. Numerical results illustrating the procedure and verifying the accuracy of the results are included. These results are compared with other theoretical calculations fo...
