    摘要:

    极光分光光谱仪成像所得重要辐射特征包括氧原子所激发的557.7、630.0、636.4 nm谱线,这些谱线和入射电离层的高能电子能通量、中高层大气粒子成分密度等都有着紧密联系.本文结合引发极光的电子碰撞反应物理机制构建氧辐射特征仿真模型,利用极光光谱图像557.7、630.0 nm谱线估计最接近真实成像情况下的入射电子能通量,实验结果表明仿真中基于假设光强比推演得到的氧辐射谱线像素预测值较真实值高估了1~1.29倍.

    Abstract:

    The significant radiation features acquired by aurora spectrometer include spectral lines at 557.7,630.0 and 636.4 nm emitted from oxygen atoms.And these lines are deeply influenced by energy and flux of high energy electrons which penetrate into ionosphere,by the particle density of middle and upper atmosphere,and so on.This paper presents a model to deduce oxygen radiation characteristics based on physical principles of electron impact reactions which cause aurora.By utilizing spectral information at 557.7 and 630.0 nm of aurora spectral image,this model estimates incident electron energy and flux which are closest to those under the practical imaging environment.Experimental results show that for oxygen radiation lines,the predicted values calculated by the presented model overestimate the true values by 1-1.29 times.
