摘　　要：详细分析了飞行器雷达罩设计过程中的基本问题。基于多目标优化设计方法建立了雷达罩结构参数求解的数学模型，给出了求解方法。考虑到雷达罩的安全使用要求，分析了雷达罩防雷击部件的基本要求，提出了设计方法，给出了防雷击部件布置的经验公式。同时还研究了用于飞行器雷达罩金属部件的吸波材料电磁波吸收机理。Some essential problems dealing with in the process of aircraft radome design are analyzed in detail. Based on the method of multi objective optimum design, mathema tics model is established to get the parameters of radome structure and then the method of optimal results is presented. Taking account the use of aircraft radome safely, basic requirements of radome lightning components are also discussed. Some experiential expressions are employed to choose the forms of lightning components and their layout. Microwave absorbing principles are investigated in detail to prevent from reflection of microwave. It is a great help to select different kinds of microwave absorbing material and to meet the needs of metallic components of radome.
