Scattering by a finite cylinder

Scattering of a plane wave by a finite, conducting, right-circular cylinder is treated by geometrical diffraction theory. Formulas appropriate for calculating radar cross-section as a function of frequency, polarisation, aspect angle and bistatic angle are presented. Calculations for two large cylinders are in very good agreement with monostatic measurements against aspect angle for four linear-polarisation combinations. Contributions from individual scattering centres are plotted. The predicted variation of the cylinder´s radar cross-section with bistatic angle corresponds to the bistatic-monostatic equivalence approximation.
