摘　　要：舰艇雷达隐身性能设计是舰艇生命力设计的重要内容,直接影响其作战效果。舰艇雷达隐身最为有效的途径是进行外形隐身设计,而舰艇主要截面在雷达波各入射角下的雷达散射截面的大小将决定舰艇整体隐身性能的优劣。本文在介绍雷达隐身性能分析常用数值方法的基础上,研究了通过对不同截面外形的雷达散射截面计算,进而得到隐身性能较好的截面外形的设计方法。文中还进行了全船隐身设计和分析,并与常规设计相比较,验证了外形截面隐身设计的优越性。The shape design considering the radar stealthy performance is a very important content for the military naval vessel vitality, and will influence the ship fighting utility directly. The most effective way to get the best stealthy performance is changing the appearance of naval vessels. In this paper, the numerical method is used to analyze the radar cross section for naval vessels with the different appearances. By comparison the RCS of vessels, a better cross sectional shape is determined. Then the whole ship with better stealthy performance is designed and compared with the common design ship. The computational results verify the superiority of stealthy design.
