Abstract: A new method for computing high-frequency RCS of objects with complex configuration, called. Curved Surface Pixel (CSP) method, is presented in this paper. The distinction between CSP method and GRECO method is described. Several different approaches of the pixel methods are analyzed. Many computation examples for spheroid, ellipsoid, cone, missile mode and aircraft mode show that the CSP method has advanced computation accuracy. -
