摘　　要：研究了舰艇外形雷达隐身优化设计问题。介绍了舰艇外形雷达隐身防护常用措施和进行雷达隐身性能评估的数值方法,提出外形隐身优化的多层次设计优化模型理论及相关数学表达式。以某型船为例,进行外形隐身截面尺寸优化,将全船隐身设计与常规设计相比较,验证外形隐身设计优化理论的正确性和优越性。The shape optimal design considering the radar stealthy performance is studied for the military naval vessels. The most effective way to get the best stealthy performance is changing the appearance of naval vessels. In this paper, the measures used in RCS reduction and the numerical analysis methods for RCS prediction are introduced firstly. Then the multilevel optimization modeling theory and mathematical formulations for optimal design considering the radar stealthy performance are proposed. By comparison the RCS of the conventional design and the optimal design, a better cross sectional shape is determined. The computational results verify the superiority of stealthy desizn and the correction of the proposed theory.
