Abstract :
The purpose of this work is to gain some insight into the RCS mechanisms for a large rectangular cavity, flush mounted in the sidewall of a finite circular cylinder. The geometry can be used to represent a structure such as a cockpit in an air vehicle. Aperture integration (AI) of the waveguide modes was used for the cavity. Creeping wave effects were accounted for via the uniform geometrical theory of diffraction (UTD). External scattering from the cylinder was handled by curved edge GTD. This AI/UTD technique was previously used for a cavity in a finite, flat ground plane. Validation of the numerical results was by comparison with the PO-based RAPPORT code.
