Abstract :
In this paper, a parametric surface is introduced to model complex targets. The high-frequency radar cross section (RCS) of the target is obtained through physical optics (PO) techniques. The PO integral on parametric patches is calculated using a numerical method. Excellent agreement with geometric optics (GO) predictions is obtained.
