Ⅰ.引言随着雷达工程,通讯工程及射电天文等技术的发展,对天线反射面的精度要求越来越高。在反射面的设计方面已出现了不少新的方法,如保形变形,最佳调整角,最佳吻合抛物面等。在结构设计分析方面,则采用了有限单元法和最优化设计。但是当反射面安装以后,为了确定它是否符合要求,还必须进行调整与检测。通过精确的检测与调整,使反射面达到设计要求而保证正常工作,因此对反射面的调整检测工作是一个很重要的环节。对于高精度天 I. INTRODUCTION With the development of technologies such as radar engineering, communication engineering and radio astronomy, the accuracy of the antenna reflecting surface is getting higher and higher. In the design of the reflector has emerged a lot of new methods, such as conformal deformation, the best adjustment angle, the best match paraboloid and so on. In the structural design analysis, the finite element method and the optimal design are used. However, when the reflective surface is installed, it must be adjusted and tested in order to determine whether it meets the requirements. Through precise detection and adjustment, the reflective surface meets the design requirements to ensure normal operation, so the adjustment and inspection of the reflective surface is a very important link.
