Polar Mount在TVRO天线中的应用与在射电天文望远镜中的应用是有重要区别的。本文在分析这种区别的同时,着重介绍了作者从实际工程结构化简出的TVRO天线Polar Mount数学模型,及严格推导出的天线指向计算公式。该公式可以作为这种天线指向调整机构设计、指向误差分析和工程改进的理论依据之一。
The use of Polar Mount in TVRO antennas is very different from that of radio telescopes. While analyzing this difference, this paper focuses on the Polar Mount mathematical model of the TVRO antenna which is simplified by the author from the actual project structure, and strictly deduces the calculation formula of antenna pointing. The formula can be used as one of the theoretical bases for the design of the antenna pointing adjustment mechanism, pointing error analysis and engineering improvement.
