基于RCS序列的空间目标识别技术综述

Overview of Space Targets Recognition Technology Based on RCS Sequence

随着科技水平的发展和人类航天活动的愈发频繁,空间目标识别技术成为国内外学者的一个热点研究领域。空间目标的RCS序列作为雷达窄带信息,对于目标识别具有一定的优势,近年来目标RCS序列在空间目标识别的价值越来越大。梳理了基于RCS序列的空间目标识别的研究现状,从空间目标尺寸估计、空间目标姿态判断与周期提取、空间目标识别特征提取和空间目标分类器设计等4个方面进行了详细的叙述,最后展望了基于RCS序列的空间目标识别技术的未来发展方向。

With the development of science and technology and the increasing frequency of human spaceflight activities,space targets recognition technology has become a hot research field for scholars at home and abroad.As radar narrowband information,the RCS sequence of space targets has advantages for target recognition.In recent years,the value of target RCS sequences in space targets recognition has been proved.This paper combed the research status of space targets recognition based on RCS sequence,and conducted a detailed review from the four aspects of space targets size estimation,space targets attitude judgment and period extraction,space targets recognition feature extraction and space targets classifier design.The future development direction of space targets recognition technology based on RCS sequence was prospected.
