Abstract本文对地球等离子体层和电离层进行了三维建模,并模拟卫星对30.4 nm极紫外线的探测过程,取得圆轨道平行束情况下的投影数据.采用改进的ART算法对所得数据进行三维重建,获得等离子体层的空间密度分布.结果表明,在投影角度覆盖180~。的情况下,重建结果很好地再现了模型中空间各点的数值.文章对实验结果从 CT重建方法的角度进行了讨论及分析.
Other AbstractIn this paper we built up a three dimensional model for the density distribution of earth plasmasphere.According to the physical procedure of 30.4 nm EUV detection,a numerical method was proposed which simulates the satellite imaging the plasmasphere along a circular orbit.To reconstruct the density distribution in such occasion a modified ART reconstruction method was worked out.Results showed that our method reconstructs the model very well.
