分析结果表明，仔细选择材料和桁架设计，结合精确的制造技术，可以为大空间天线带来非常精确的表面。本文的目的是检查各种类型的结构配置的这些关系。对各种天线直径和焦距以及辐射信号波长下桁架式和圆顶式结构可实现的精度进行了比较。
Analytical results indicate that a careful selection of materials and truss design, combined with accurate manufacturing techniques, can result in very accurate surfaces for large space antennas. The purpose of this paper is to examine these relationships for various types of structural configurations. Comparisons are made of the accuracy achievable by truss- and dome-type structures for a wide range of diameter and focal length of the antenna and wavelength of the radiated signal.
