厘米级空间碎片建模研究

Research on Centimeter-level Space Debris Modeling

空间碎片对航天器的威胁日益得到国际上的高度重视,各国纷纷开展独立或联合研究,对空间碎片进行观测、跟踪及预警。空间碎片环境建模也成为该领域的研究热点之一。通过建模可以描述当前的空间碎片环境,预测未来长期或短期内空间碎片环境的演化情况,从而对人类的相关太空活动进行建设性的指导。本文调研并梳理了国际上对厘米级小碎片建模的相关研究工作,旨在为后续厘米级小碎片的研究提供较为综合、系统的参考。

The threat of space debris to spacecraft has received increasing international attentions,and countries have conducted independent or joint research to observe,track and warn space debris.Space debris environment modeling has also become one of the research hotspots in this field.Modeling can describe the current space debris environment and predict the evolution of the space debris environment in the long-term or short-term future,thus providing the constructive guidance for the human related space activities.This paper investigates and combs the international research work on modeling centimeter-scale fragments,and aims to provide a comprehensive and systematic reference for the subsequent research on small-scale centimeter fragments.
