摘要/Abstract

摘要：

500 m口径球面射电望远镜(five-hundred-meter aperture spherical radio telescope, FAST)是近年建成的重大科学装置, 其高效运行依赖于对馈源仓的高精度定位。当前基于全站仪测距的馈源仓定位系统在雨雾等恶劣天气中无法有效工作, 降低了FAST工作时长。针对此问题，提出一种基于微波测距的新方案, 有望在满足馈源仓定位精度的同时, 显著改善FAST的运行效率, 使之实现全天候全天时工作。深入研究了微波测距定位系统中亟待解决的若干关键科学问题, 初步给出了系统方案与技术路线。根据理论分析, 该微波测距系统的定位误差优于±5 mm, 可达到设计要求。

关键词: 500 m口径球面射电望远镜, 微波测距仪, 多频相位测距法, 系统误差校正

Abstract:

Five-hundred-meter aperture spherical radio telescope (FAST) is an important scientific device built in China in recent years. Its efficient operation depends on the high-precision positioning of the feed cabin. The current feed cabin positioning system based on total station ranging cannot work effectively in severe weather such as rain and fog, which reduces the working time of FAST. In this paper, a new scheme based on microwave ranging is proposed, which is expected to not only meet the positioning accuracy of feed cabin, but also significantly improve the operation efficiency of FAST, enabling it to work all weather and all day. In this paper, some key scientific problems to be solved in the microwave ranging positioning system are studied deeply, and the system scheme and technical route are given preliminarily.

Key words: five-hundred-meter aperture spherical radio telescope (FAST), microwave range finder, multiple frequency phase ranging method, system error correction
