Near-zone scattering by plates, cylinders, and cones

The near-zone monostatic scattered fields of flat plate, circular cylinder, and finite right circular cone targets are considered in this communication. The near-zone scattered fields were measured using a Scientific-Atlanta precision EM field probe, and the near-zone fields were computed using the geometrical theory of diffraction (GTD). Good agreement between measurements and predictions resulted. These results indicate that the geometrical theory of diffraction is an accurate descriptor of near-zone scattering.
