RCS (Radar Cross-Section) of a Finite Length, Perfectly-Conducting Cylinder on a Planar,Uniform Impedance Surface.

摘要

The radar cross-section (RCS) of a finite length, perfectly-conducting circular cylinder on a uniform impedance surface is calculated via the geometrical theory of diffraction (GTD). The cylinder is oriented such that its axis is normal to the surface impedance plane. It is found that the effect of the surface impedance is, in general, to enhance the RCS over that without the surface impedance. Both these calculations are presented for comparison. The RCS is, of course, dependent on the angle of incidence, polarization and the frequency of the incident wave; these effects are also investigated.
