摘要：

基于电波电离层传播基本理论和高功率微波大气传输机理，讨论了低频端超宽谱高功率微波 (HPM)低电离层中的自作用效应，得到了强场条件下自作用因子表达式，分析了强场条件下电场强度、电波频率、电子碰撞频率、电子密度、传播距离等参数对自作用效应的影响. 仿真结果表明，初始场强振幅大、频率高、电子密度越大、传输距离越远，自作用效应越明显.

Abstract:

Based on the radiowave propagation theory and high power microwave (HPM) atmosphere propagation mechanism in ionosphere, the selfinteraction effects of ultrawide spectrum HPM of lowerfrequency side are analyzed. The formulae for selfinteraction factor are obtained in the case of intense field. And the influences on selfinteraction effects caused by the electricfield intensity, the radiowave frequency, the electron collision frequency, the electron density and the propagating distance, are also discussed. Simulations show that the selfinteraction effects will appear more obviously with the increase of the amplitude of the initial field intensity, the frequency of ultrawide spectrum HPM, the density of electron density, and the propagation distance. .
