【摘要】 高轨空间碎片(一般指轨道高度高于20000公里)的光学观测是近年来空间碎片研究领域中重要的研究主题之一。它在目标的探测、跟踪、识别等领域有着广阔的应用前景。目前对其物理特性的有效研究手段主要是基于时间序列的测光观测,基于同时性的多色测光观测,基于低色散的光谱观测以及基于偏振的光学观测。该文将重点从此四个方面回顾目前的研究现状和常用的处理方法,并对研究难点和未来发展趋势作了分析和阐述。更多还原

【Abstract】 Optical observations of high apogee space debris is currently one of active research topics in the domain of space debris.This strong interest is driven by a wide spectrum of promising applications in many area such as space object detecting,tracking,and identification etc.Four major methods in the physical characteristics of high apogee space object involved in time series photometric photometry,Simultaneity Color-Color photometry,Spectroscopic observations,and Photopolarimetric observations are described.This paper provides a comprehensive review of recent developments and general applications of optical observations involved in the above four issues.At the end of this review,some discussions on research challenges and future directions in this field are also provided.更多还原
