Abstract :
With the development of computer-aided design/computer-aided manufacturing (CAD/CAM), nonuniform rational B-spline (NURBS) is applied in describing models broadly, for example: aeronautic, automobile, ship and so on. NURBS is a very excellent method describing models, but it is harder than Bezier on computation. So the NURBS surfaces are transformed into Bezier surfaces. Thus, PO is used to compute the RCS of model with Bezier surfaces in this paper.
