Abstract:
In this paper, a set of formulas to analyze the scattering from open-ended rectangular cavity is presented on the basis of Shooting and Bouncing Ray (SBR) method. By analyzing the ray paths inside the cavity, the Physical-Optics (PO) integration on the aperture is carried out in a close form. Using closed-form solution, the Radar Cross Section (RCS) of cavity in high frequency can be studied sententiously and accurately. All the peaks and nulls in the RCS plot of cavity are predicted successfully with the formulas deduced in the paper, and a 3-D scattering pattern of rectangular cavity is simulated by the proposed method.
