Abstract
Predicting RCS (radar cross section) of aircraft is the basic and important content of technology. A technique for prepositive disposal in predicting RCS of aircraft by using computer graphic method and NURBS (non-uniform rational B-spline) surface and Bezier surface is presented. The technique can realize the shadowing calculation, regroup of geometrical model and the transfer from NURBS surface to Bezier surface. The result proves that the technique possesses the character of good shadow effect and high precision which is differ from former predicting technique which is based on face element.
