Radar scattering from bodies of revolution using an efficient partial differential equation algorithm

A technique is presented for solving the problem of scattering by a three-dimensional body of revolution using a partial differential equation (PDE) technique in conjunction with a 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 on an asymptotic expansion derived by Wilcox (1956). Numerical results illustrating the procedure and verifying the accuracy of the results are included.>
