Abstract研究了磁层-电离层-热层耦合星座(MIT)卫星计划中高能中性原子成像仪(NAIS-H)探测方案的原理设计和模拟仿真.以双星中性原子成像仪设计思想为基础,依据MIT卫星计划的总体科学目标和磁层卫星的轨道环境及相应自旋姿态,给出中性原子成像仪的技术架构,并针对地磁偶极场的环电流模型进行了模拟仿真.仿真结果表明,所研制的NAIS-H以其高时空分辨能力适用于监测和反演磁暴期间磁层等离子体的全球动力学过程.
Other AbstractEnergetic Neutral Atoms (ENA) are generated within the Earth's magnetosphere through charge exchange between magnetically trapped energetic ions and cool neutral gasses. An ENA imager can potentially record the arrival directions and energies of magnetospheric EN As, as well as provide (indirectly) global images of the spatial and energy distributions of their parent ion populations. Preliminary technical configuration and simulation of the Neutral Atom Imaging System for high energy neutral atoms (NAIS-H) designed for the Chinese Magnetospheric-Ionospheric-Thermospheric (MIT) mission are described. In inherited the design concept of NUADU and focus on the main scientific objective of MIT and t.lie orbit, a preliminary technical overview of this instrument is provided. The simulations under a dipolar magnetic field model show tliat the instrument has the capability to monitor global dynamic processes with high temporal and spatial resolution.
