摘要
本文讨论了中央开孔的修正型卡塞格伦天线的最佳吻合原理和计算方法。对上海天文台25米射电望远镜天线,在三种俯仰角状态下进行了主面偏差实测及最佳吻合,给出偏差值及等值线图。
The best-fit principle and computational method of a corrected Cassegrain antenna which has a circular hole at reflector surface centre are discussed in this paper. Measuring the reflector surface deflection of the 25 metre antenna at Shanghai Observatory at three elevation positions, the best-fit results are obtained and the deflection values and contour diagrams are also given.
