Radar cross section of curved plates using geometrical and physical diffraction techniques

Geometrical and physical optics techniques, supplemented by their respective extensions, i.e., geometrical and physical diffraction, are applied to the problem of finite cylindrically curved plates. Numerical calculations of the radar backscattering cross sections were made, and a graphical comparison of these methods with experimental results is made. Keller's and Ufimtsev's theories axe discussed and compared as they apply to this problem.
