摘要
介绍了长波天波传播特性,阐述了罗兰C天波信号实测试验的原理,通过对试验数据的研究分析,得出罗兰C天波信号覆盖范围、修正精度及昼夜变化规律,给出了天波使用的有关建议。
First, the characteristics of Loran-C skywave transmission and the principles of Loran-C skywave signal testing are introduced in this paper. According to the analysis of testing data, the coverage areas, the correct precision and the rule of diurnal change are gained. Finally, the suggestions for skywave are presented.
