| 摘 要： | 本文分析了在新乡和临潼两地同时接收Omega导航台的H台和C台信号的相位变化。从四条传播路径的测试结果中,分析了TE模的存在以及特点。通过一组导出的方程组,从C台信号的测试数据中,用实验回归法确定出TE1模的激励因子。结果表明,VLF信号夜间向西传播时,测出的TE1模的激励因子看来比理论给出的数值要大。

| Abstract: | In this paper, phase changes of signals from H station and C station of the Omega system are analysised, the signals being simultaneusly received at Xinxiang and Lingtong. The existence and the characteristics of TE modes are determined from the measured data for the four possible propagation paths.The excitation factor of TE1 mode is obtained by solving a set of leading equations with the regression method. However the value of the faptor deduced from experimental result seems to be larger than the theoretical one, when propagation of VLF radiowaves over east-west paths at night. |
