空間碎片撞擊在軌感知技術(shù)研究綜述

A review of studies of onboard sensor systems for space debris impact on spacecrafts

摘要: 隨著航天發(fā)射活動的日益頻繁，空間碎片環(huán)境隨之惡化,。為了應(yīng)對空間碎片的撞擊威脅,，人們提出了用空間碎片撞擊在軌感知系統(tǒng)實(shí)時監(jiān)測航天器在軌遭受空間碎片撞擊的情況。文章在對國內(nèi)外相關(guān)研究機(jī)構(gòu)研究成果的調(diào)研基礎(chǔ)上,，介紹了國內(nèi)外在空間碎片撞擊在軌感知技術(shù)領(lǐng)域的研究現(xiàn)狀,，對各國基于超高速撞擊聲發(fā)射技術(shù)的空間碎片撞擊在軌感知技術(shù)的發(fā)展?fàn)顩r進(jìn)行了全面評述，重點(diǎn)介紹了國內(nèi)的研究進(jìn)展,。最后基于國內(nèi)航天事業(yè)需要,，探討了未來發(fā)展方向。

Abstract: With the increase of space activities, the space debris environment becomes deteriorated. To deal with the threat from space debris, a new concept of the onboard monitoring system is to locate the position of the impact point and evaluate the effects of the impact in real time. This paper reviews the studies at home and abroad in the field of onboard monitoring technologies, especially, those based on acoustic emission (AE) technology, focusing on the domestic research progress. The new trends of the development are discussed according to the actual development demands of China space programs.
