摘　　要：针对目前对大型高性能雷达天线罩的迫切需求,介绍了一种气承式雷达天线罩。对充气天线罩四个组成部分——罩体、基座、压力调节系统、环境控制系统的设计思路分别进行了阐述,并对天线罩的抗风能力进行了计算分析。结果表明:通过选择合适的柔性蒙皮材料和合理的充气内压,天线罩在46.1m/s风速作用下仍具有较强的刚度,整体变形较小,可以满足雷达的使用要求。An air‐supported radome design method is proposed to meet the needs of the high‐performance ra‐dars .The inflatable radome consists of shield ,base ,pressure regulation system and environment control system ,whose design methods are introduced separately .The wind‐proof capacity of radome is analyzed . The simulation shows that the combination of suitable pellicle strength and pressure enable the radome to maintain sufficient stiffness and small deformation when the wind velocity is 46 .1m/s ,which can meet the requirement of radars .
