摘要
雷达目标微动特性是当前目标探测与识别领域的新兴研究方向和热点课题,随着近10年的发展积累了一些研究成果。本文重点综述了微动目标雷达回波调制效应、微动特征提取、微动目标雷达成像、微动特性测量及雷达波形设计等方面的研究成果,部分成果已应用于空间/空中目标探测与识别等领域。本文的研究成果及结论为进一步推动国内微动特性研究提供参考和基础。
The analysis of radar targets in micro-motions is an emerging technical hotspot in the field of radar target acquisition and identification, and much progress has been made during this decade. Some scientific issues related to micro-motion analysis are discussed in this paper, such as the modulation in radar returns induced by micro-motions, the extraction of micro-motion features, the radar imaging for targets in micro-motions, and the radar waveform designing oriented to micro-motion features. Some of the research achievements have already applied in the fields of aerial and spatial target acquisition and identification.
