Computer Modeling of High Power Radio Wave Propagation in the Lower Ionosphere

指向高层大气和电离层的高功率无线电波可以在不同频率产生成分、电子密度、光发射和其他无线电波的变化。其中许多影响的原因仍不清楚，对于给定的功率和频率输入，究竟会发生什么扰动在理论上仍然无法解释。这个项目是设计一个高功率无线电波在低电离层传播的一维模型，并将该模型与新的实验观测结果进行比较。基于动力学理论的方法将被用来讨论单个脉冲、一系列脉冲以及连续波的传播。将提供无线电波的各种参数的计算，例如有效功率、频率、极化、脉冲持续时间和脉冲间隔时间。这些计算将在白天和夜间电离层条件下进行。

High powered radio waves directed to the upper atmosphere and ionosphere can produce changes in composition, electron density, optical emissions and other radio waves at various frequencies. The cause of many of these effects is still unknown and just what perturbation will occur for a given power and frequency input is still theoretically unexplained. This project is to design a one dimensional model of the propagation of powerful radio waves in the lower ionosphere and compare this model to new experimental observations. An approach based on kinetic theory will be used to discuss propagation of a single pulse , a series of pulses as well as a continuous wave. Calculations will be provided for varying parameters of the radio wave such as effective power, frequency, polarization, duration of the pulse and time between pulses. These calculations will be done for both daytime and nighttime ionospheric conditions.
