Radar Cross Section （RCS） is the important factors of defense system radar detection and target identification. To the early warning radar in missile penetration, the attitude angle variation law with time on the basis of calculating trajectory is analyzed, then estab- lished electromagnetic incident angle model. Through simulation analysis, the RCS characteristics of the mid course with the change of the e- lectromagnetic incident angle is obtained. The study of this paper has certain reference value for reasonable planning ballistic missile attitude and reducing defense system radar detection and tracking ability.
