| 摘 要： | 针对核爆电磁脉冲沿地面传播问题,引入快速傅立叶变换及其逆变换,采用"波跳"理论,对低频/甚低频(LF/VLF)频段电磁信号沿地面-电离层进行了数值计算。计算结果表明,随传播距离增大,地波衰减速度比天波快,天波与地波之间的时间延迟减小。

| Abstract: | It calculates the LF/VLF wave of NEMP propagation along the earth's surface.The earth-wave and the sky-wave are taken into account in the calculation.With the distance increase.the earth wave attenuates fast than the sky wave,and the time difference between the earth wave and the sky wave is reduced. |
