The relation between the spectra of the lightning electromagnetic pulses (LEP) and the structure of the lower ionosphere is discussed by means of the mode theory of the wave propagation in the earth-lower ionsphere waveguide. The effective parameters of the ionosphere can be deduced by use of the relation between these parameters and the frequencies corresponding to the minimum in the spectra of the LEP. It is obtained from the measured data of the LEP that the effective parameters of the exponential lower ionosphere are β= 0.3km-1 and hi=70 km during the day time, and β = 0.5km-1 and hi = 88km at night. The temporal and geographical variations of the lower ionosphere can also be observed.

从低电离层—地面波导中电波传播的波导模理论出发,分析了雷电产生的电磁脉冲(LEP)谱随距离变化与低电离层结构之间关系。利用LEP谱中干扰最小值时的频率与指数电离层模式参量的关系得出低电离层等效模拟参量。从我们观测出的LEP数据得出指数电离层等效参量是:在白天β=0.3km~(-1),h_i=70km;在夜间β=0.5km~(-1),h_i=88km。并指出使用这种方法可以观测出低电离层在时间上和地理位置上的变化。
