Scattering from cylindrical structures with various end‐cap shapes

The scattered field from a cylindrical structure near the forward direction is computed using the Kirchhoff approximation of scattering from a screen. The effects of varying the shape of the end‐caps are examined by carrying out target strength computations for various shapes. The cylindrical region is modeled to be impenetrable while the effects of varying the reflectivity of the end‐cap regions are examined. [Work supported by ONR.]
