Abstract

Micro-Doppler signature is one of the physical characteristics of the target. The radar signature of a target with micro-motion can make fine characterizations of the shape, structure, and moving state of target, which reflects the nonstationary property of a radar signal. Hence, it has great superiority in the analysis of sea clutter and target detection in the case of high sea states based on the micro-Doppler theory. In this paper, to show the need for micro-Doppler, the modeling of scattering clutter from time-varying sea surface and analysis methods of sea clutter Doppler are first reviewed based on the principles and characteristics of micro-Doppler. Then, applications and technological approaches of micro-Doppler in sea surface target detection are introduced from the perspective of micro-motion target modeling and detection methods of micro-motion signatures. Finally, future research interests are highlighted based on problems experienced in present studies.

微运动理论在海面目标探测中的应用与展望
微多普勒信号是目标的物理特征之一。微运动目标的雷达特征可以很好地表征目标的形状、结构和运动状态,反映了雷达信号的非平稳性。因此,基于微多普勒理论的海杂波分析和高海况条件下的目标检测具有很大的优势。本文首先从微多普勒的原理和特点出发,综述了时变海面散射杂波的建模和海杂波的分析方法,说明了微多普勒的必要性。然后从微运动目标建模和微运动特征检测方法两方面介绍了微多普勒在海面目标检测中的应用和技术途径。最后,针对目前研究中遇到的问题,提出了未来的研究方向。
