相路径与群路径同斜向传输距离的关系

本文从电离层为均匀球面分层的假设, 得出了一组联系斜传播中相路径P、群路径P'和传输距离D的微分关系式, 导出了P～D和P'～D曲线的斜率公式, 并简短地讨论了这些曲线的可能应用. 

Relations Between Transmission Distance and Phase/Group Path for Oblique Propagation

In this paper, a set of differential equations is obtained which relates phase path P, group path P' and transmission distance Dfor oblique propagation under the assumption that the ionosphere is spherically stratified. The expressions with regard to the P-Dand P'-Dcurve slopes are also derived, and a possible application of these curves is briefly discussed.
