Abstract

Increasing frequencies of perspective space mirror antennas functioning leads to a significant tightening of the requirements for the accuracy and stability of the reflecting surface of the used reflectors. However, the provision of high requirements is technically difficult to implement. Hence, the problem of Pareto-optimal design of parabolic antenna reflectors with a relatively high signal amplification coefficient and minimum requirements for the accuracy of the reflecting surface profile is formulated. We obtained analytical estimates for Pareto fronts of various ranks characterizing the accuracy of the profile of the reflecting surface of the antenna parabolic reflector depending on its diameter and the range of operating frequencies required to ensure a high signal gain.

透视频率的空间镜天线抛物面反射镜反射面精度的帕累托最优要求

摘要

透视空间镜天线工作频率的增加导致对所用反射器的反射表面的准确性和稳定性的要求大大提高。但是，高要求的提供在技术上难以实现。因此，提出了具有相对高的信号放大系数和对反射表面轮廓的精度的最低要求的抛物面天线反射器的帕累托最优设计的问题。我们获得了各种等级的帕累托锋面的分析估计，这些估算值表征了天线抛物面反射器反射面的轮廓精度，具体取决于其直径和确保高信号增益所需的工作频率范围。
