Simulation of RCS of Battleplan by the Software Feko

There is a method to compute the radar cross section(RCS) by the soft ware FEKO.This paper presents the author's modeling method and skill.and there is a 3D model from the soft ware Unigraphics and a mesh model from the soft ware ICEM CFD.The RCS of overseas battleplan was caluated and precision of this method was believable.
