| 摘 要： | 文章对高功率微波(HPM)在低电离层中的传输特性进行了研究,分析了低电离层中HPM的自作用效应,推导了HPM在低电离层中传输的自作用因子和电场振幅同初始场强的关系,并进行了数值模拟。计算结果表明,在一定条件下HPM进入低电离层时,其振幅将趋于一个饱和值,本文估算出了HPM在低电离层中传输时的场强饱和阈值。

| Abstract: | In this paper,studying the theory of High Power Microwave(HPM)propagation in lower ionosphere.The analytical self-action effect of HPM in lower ionosphere,and the relation of self-action factor and electric field amplitude with the initial electric field is analyzed when HPM propagates in lower ionosphere,and then simulate numerically.The conclusion shows that electric field amplitude will trends to a saturation threshold when HPM comes into lower ionosphere at a special condition.At the end of the paper,it is shown that the saturation threshold of electric field. |
