摘要: 简述了某型号雷达反射面天线的结构特点,并从材料选择、模具设计、天线结构优化和成型工艺等方面对天线成型进行了研究和讨论。采用热补偿方法对模具成型面进行了修补,利用正交试验设计对天线固化参数进行了优化。结果表明,天线厚度误差控制在±0.05 mm内,天线型面均方根差(RMSE)≤0.1 mm,天线副瓣电平为-30 db(34.468 GHz),结构、电气性能指标满足设计要求。

Abstract: The structural characteristic of a certain type of radar reflector antenna was introduced in this paper briefly. Then, material selection, mould design, structure optimization, manufacture process were discussed and studied mainly based on antenna molding process. The mould surface was repaired by thermal compensation method. Simultaneously, the antenna curing parameters were optimized by orthogonal experimental design. The results demonstrate that the thickness of antenna can be controlled in the range of ±0.05 mm, the root mean square error (RMSE) of antenna surface is less than 0.1 mm, and the side lode level of antenna is able to reach -30 db (34.468 GHz), all of which can meet design requirement.
