  • 摘要: 传统雷达能够实现对运动目标的探测,但当目标速度矢量方向与电磁波传播方向垂直时,其角向运动信息难以有效获取,从而在旋转目标运动趋势感知方面存在一定的探测盲区。携带轨道角动量(OAM)的涡旋电磁波具有螺旋相位结构和环状辐射特性,在与旋转目标相互作用时会产生旋转多普勒效应,从而为获取目标的角向运动信息提供了新的技术途径。近年来,基于涡旋电磁波旋转多普勒效应的目标探测方法引起了国内外研究人员的广泛关注。本文系统综述了涡旋电磁波旋转多普勒探测技术的发展历程与研究进展,重点介绍了微波波段相关研究成果,包括基于相位与频谱特征的旋转多普勒探测方法,基于OAM模式特性的旋转多普勒探测方法以及基于涡旋电磁波的目标微动探测方法。最后,本文对现有研究中的主要问题进行了系统梳理,并对未来的发展方向及潜在应用前景进行了展望。
