摘要:
随着太空探索活动的逐年增多,人类对空间碎片的探测显得越发重要。文章首先介绍了探测空间碎片的意义及其常规的光电探测方法,并分析了探测空间碎片的主要难点;在此基础上,结合空间碎片的具体特征,提出一种对空间碎片进行探测与识别的新方法,即将成像、光谱、偏振三个光学基本量同时使用,通过多元特征融合等识别技术,实现对空间暗、弱、小碎片的高效探测,并对新方法中的关键技术进行了分解和可行性分析。

Abstract:
With human space exploration activities increased year by year, observation of space debris is particularly important. The significance of the observation of space debris and conventional method of photoelectric observation are introduced in this paper, and the main difficulties with the observation of space debris are analyzed. On this basis, according to the specific characteristics of the space debris,a new method for detection and identification of space debris is proposed, which is, three base quantity including imaging, spectrum, polarization are used simultaneously for the effective detection with space dark, weak, little pieces through multiple feature fusion recognition technology. Then, decomposition of the key technologies and feasibility analysis are demonstrated.
Key words:  space debris;polarization spectral imaging;photoelectric observation
