雷达罩的综合优化设计

在分析对比现有的雷达罩设计方法基础上，针对某型直升机机栽雷达罩，研究了雷达罩设计过程中的基本问题、关键技术和综合优化设计方法，运用三维射线追踪法进行了计算机辅助设计，给出了布设防雷击部件的经验公式，讨论了吸波材料选择与喷涂的基本准则。电测结果表明：加罩后的功率传输系数、反射瓣、雷达辐射特性等指标的实测数据与计算值符合较好，满足了设计要求。

Integrated Optimizing Design of Radome

Researches on essential problems, key techniques and integrated designing methods of airborne radome in helicopter are made on basis of existing designing methods, and a computer aided design(CAD) of airborne radome is conducted by means of 3D ray tracking technique.The experiential expressions are given to lay components of preventing lightning, and selection and spraying criteria of microwave absorbing material are discussed. Electric experimental results show that measured data such as power transmission coefficient, reflection-lobes and radiation characteristic of antenna with radome are in agreement with calculated data and satisfy the design requirements.
