【摘要】 提出了近地空间环境要素三维建模的静态模型和实测模型。根据近地空间环境各要素的特点,首先利用各种静态模式和实测数据构建三维空间数据场。然后对数据场进行六面体单元剖分,其中对实测得到的空间数据利用雅克比矩阵转换为规则六面体数据。最终,分别给出了中性大气、电离层等离子体、地球基本磁场和地球辐射带的几何模型,提出了一种适合于近地空间环境要素仿真的通用三维可视化方案。更多还原

【Abstract】 The static model and survey model about the near-earth space environment element were advanced. On the base of each near-earth space environment element specialty, the relevant 3D data field was established by every static model and the survey data, and then the data field was partitioned off to hexahedron, thereof the survey spatial data was switched into the regular hexahedron data by Jacobi matrix. Finally the geometry model of the neutral atmosphere, the ionospheric plasma and geographic magnetic field and the earth radiation belt were given, and the universal 3D visualization scheme for the near-earth space environment element simulation was advance.更多还原
