摘要

摘要:该文提出了基于多普勒谱分析的无源相干雷达(PCR)运动目标检测的方法,将雷达系统接收到的外辐射源连续波信号分段并等效成脉冲串信号,利用脉冲压缩和多普勒处理技术对目标进行检测及定位。该方法以脉冲多普勒(PD)雷达的理论为基础,说明了匹配滤波时连续波信号可以划分成脉冲串信号等效处理,对应给出了无源雷达信号分段及多普勒谱分析的具体方法。文中还详细推导了该方法与传统的计算互模糊函数(CAF)方法之间的数学联系,确立了分段参数的设置准则,在几乎不影响目标积累增益的前提下,计算效率可提升 3 10 ~ 5 10 倍。仿真数据和实测数据分别验证了该方法的有效性。关键词:无源雷达;动目标检测;匹配滤波;多普勒谱分析中图分类号: TN957.51 文献标识码: A 文章编号: 2095-283X(2013)02-0247-10 DOI: 10.3724/SP.J.1300.2013.20081

期刊介绍： Journal of Radars was founded in 2012 by the Institute of Space and Astronautical Information Innovation of the Chinese Academy of Sciences (formerly the Institute of Electronics) and the China Radar Industry Association (CRIA), which is located in the high-end academic journal and academic exchange platform in the field of radar, and is committed to promoting and leading the scientific and technological development in the field of radar. The journal can publish Chinese papers and English papers, and is now a bimonthly journal. Journal of Radars focuses on theory, originality and foresight, and its scope of coverage mainly includes: radar theory and system, radar signal and data processing technology, radar imaging technology, radar identification and application technology. Journal of Radars has been included in domestic core journals and foreign Scopus, Ei and other databases, and was selected as ‘China's high-quality science and technology journals’, and ranked the first in the category of electronic technology and communication technology in the ‘Chinese Core Journals List (2023 Edition)’.
