空间碰撞碎片云探测识别与快速编目能力评估
Evaluation of detection,identification and rapid cataloging capabilities for space debris cloud
摘要
Abstract
Advancements in space-ground integrated surveillance techniques have expanded detection cov-erage and reduced object revisit times,enabling the collection of multiple orbit tractlets of new debris with-in hours of an event and thereby facilitating timely tracking and cataloging.This study evaluates the detec-tion and cataloging capabilities for monitoring debris clouds using space-based optical systems.Utilizing historical two-line element data,the identification and cataloging potential of debris generated by the COS-MOS-2251/Iridium-33 satellite collision were analyzed,assuming a space-based optical detection constel-lation of 24 satellites.Results indicate that 99%of new debris fragments can be resolved within 20 min-utes post-collision.Analysis of randomly selected samples of 100 debris fragments from each satellite re-vealed that 81%of COSMOS-2251 debris and 87%of Iridium-33 debris possess at least 10 observable tractlets within one day following the collision.Considering all observable tractlets within this timeframe,70%of COSMOS-2251 debris and 73%of Iridium-33 debris were successfully cataloged.These findings demonstrate that a well-designed space-based optical surveillance system can catalog over 70%of new de-bris resulting from space collisions within one day.关键词
