摘要: 文中用实际的电离层参数,具体地估算了在典型发射条件下,极低频脉冲调制的高频电波加热北京、上海、海口上空电离层所能产生的极低频电流强度。计算的出发点是电子的能量方程,运用迭代法对处理脉冲调制问题作了改进。用此算法同时研究了典型中纬度电离层的加热特性并与以往对高纬度的结果进行了比较。

Abstract: The strengths of the ELF currents produced by heating the iono-spheres over Beijing, Shanghai and Haikou by powerfully modulated HF wave are calculated under a typical transmitting condition, using the practical parameters of the ionospheres. The start point of the calculation is the electron energy equation, however, a new iterative method is developed to treat the pulse modulation. This algorithm is also applied to study the heated properties of the ionosphere at typical middle latitudes and the results are compared with that by previous authors for high latitudes. -
