星载毫米波反射面天线结构

“神舟4号”飞船的多模态微波辐射计天线的工作频率跨到毫米波段．这在我国过去的航天器天线中尚未遇到．采用了计算机机电热一体化设计手段，从材料的选择入手，把最佳的电性及结构设计、先进有效的制造、检测与装配技术有机地融为一体之后，保证了天线最终的高精度指标．本文从高精度反射面天线的要求出发，从设计、分析、实现以及验证多方面说明星载反射面天线形面高精度的控制与实现．

THE STRUCTURE OF MILLIMETER-WAVE REFLECTOR ANTENNA ON SPACECRAFTS

The operation frequency band of microwave radiometer on SZ-4 spaceship is located up to millimeter wave, This is hither to unprecedented in development of our spacecraft antennas. By means of computer aided integrated method for mechanical, electrical and thermal design, beginning with choice of materials the optimal design on electro-and structure has been combined with manufacture and assembly technology effectively to guarantee the minimum deformation of the reflector. This paper describes controlling and realization of high accuracy of reflector shape.
