由高能电子引起的卫星内部带电,是危害地球同步轨道卫星主要的空间环境效应之一.内部带电的物理机制和相应的卫星设计规范研究,近年来受到国际空间界的高度重视.本文用蒙特卡罗方法,通过模拟高能电子对电介质轰击后在介质中产生电荷沉积,计算了轰击后电介质内部最大电场强度,并进而分析了电介质内部电场与电子能量、屏蔽厚度及介质厚度的关系.该结果对卫星设计有重要参考价值. Charged by high-energy electrons inside the satellite is one of the main space environmental effects that jeopardize the geosynchronous orbit satellite.The research on the physical mechanism of internal charging and the corresponding satellite design standards has been highly valued by the international space community in recent years.In this paper, Luo method, by simulating the high-energy electron bombardment of the dielectric charge generated in the dielectric deposition, calculated after the bombardment of the maximum internal electric field strength of the dielectric, and then analyzed the dielectric internal electric field and electronic energy, shielding thickness and dielectric thickness of the relationship between the results of Satellite design has important reference value.
