摘要
本文针对天线极轴式调整机构进行了理论分析,严格推证出完整、准确的理论计算公式。并运用计算机进行了大量的误差分析计算,给出了在不同纬度上最佳偏置角ψ的数值和天线最佳极轴角的数值。按这些数据调整天线指向,天线的极轴不再平行于地轴,与目前国外资料中给出的天线极轴必须平行地轴的理论相比,本文的方法可以实现更高的跟踪精度和更大的跟踪范围,给实际使用提供了重要数据。
This paper gives the optimal data of the deflective position angles φ and the polar axis angles of the antenna on the different latitudes, on which, having adjusted the orientation of the antenna, we can come to the conclusion that the polar axis is no longer in parallel with the earth axis. Compared with the theory that the polar axis should be in parallel with the earth axis, which appears in the literature published abroad in recent years, the method given in this paper will provide higher accuracy and wider range for tracking object and has provided important data for practical engineering use.
