摘要

摘要: 基于稳态电子能量和动量方程,结合2009年8月电离层加热实验中非相干散射雷达实测的电子密度、电子温度和离子温度对反射高度附近的电波能量吸收率进行了估算。根据计算结果,可得到显著的电波能量吸收率的空间分布结构,能量吸收基本呈近高斯分布,但结构在横向和纵向上并不沿能量吸收中心对称。0.6MHz附近,电波能量吸收率随频差变化的曲线存在锐边界,临界状态下时(两组加热机制的交界)才会取得最佳的加热效果,这对电波能量吸收率经验和半经验模型的建立有重要意义。

Abstract: Based on energy and momentum equations, the energy absorption flux near the reflection height is calculated by using the electron density, electron temperature and ion temperature measured in the heating campaign on August 16-19 2009.It is shown that the energy absorption flux is close to Gauss distribution, but the structure is not symmetric along beam absorption centre.The curve of absorption maximum with frequency difference exists break point near 0.6MHz, and we can carry out an optimization heating in a critical state, which is important for building the experiential and semi-experiential model of energy absorption flux.
