摘要

本文研究了通过优化星载和地面终端接收天线方向图以降低天线温度来改善卫星链路质量的概念。精确的天线温度是通过考虑天线覆盖范围内陆地和水体的温差来计算的。优化过程考虑了天线方向图中的温度分布，对天线孔径分布进行了优化。类似的概念也可用于空间和射电天文学应用。

Communication link improvement through antenna optimization for satellite, space, and radio astronomy systems

This paper studies the concept of improving the satellite link quality by optimizing the pattern of the receive antenna on board the satellite and at the ground terminal to reduce the antenna temperature. Accurate antenna temperature is calculated by accounting for the temperature difference between land and water bodies in the antenna coverage. The optimization process works on the antenna aperture distribution taking into account the temperature distribution in the antenna pattern. Similar concepts can be used for space and radio astronomy applications.
