适于磁层中性原子威像探测的一般是运行在磁层高度的极轨自旋稳定卫星。利用设置在不同仰角方向的探测器通过卫星自旋进行方位角扫描以实现二维中性原子成像探测。这样以来,卫星自旋轴的取向就是我们选择中性原子二维图像的仰角和方位角分布的依据。为了提高角分辨,我们总是希望把垂直于自旋轴方向的探测器时准主要成像位置。考虑卫星在极区的最佳遥测位置,我们选择卫星自旋轴垂直于轨道面将最有利于中性原子的成像探测。对于三轴稳定卫星,我们可以利用多组硅条探测器设计二维中性原子成像仪。
Suitable for magnetospheric neutral atomic image detection is generally run at the height of the polarosphere spin-stable satellite. Azimuthal scanning by satellite spins with detectors located in different elevation directions to achieve two-dimensional neutral atomic imaging detection. Since then, the orientation of the satellite spin axis is the basis for our choice of elevation and azimuthal distribution of two-dimensional images of neutral atoms. In order to improve the angular resolution, we always hope that the detector will be perpendicular to the direction of the spin axis quasi primary imaging position. Considering the satellite’s best telemetry position in the polar region, we choose the satellite spin axis perpendicular to the orbital plane to be most conducive to imaging detection of neutral atoms. For three-axis stable satellites, we can design two-dimensional neutral atomic imager using multiple sets of silicon bar detectors.
