摘　　要：超宽带(UWB)雷达人体行为感知主要研究如何利用人体目标电磁散射回波对位置、行为、意图等进行判别,是光学感知手段的有益补充,应对无光照、地物遮挡、非视距等情况下的应用场合。该文将超宽带雷达人体行为感知研究方法分成基于空间位置和基于微动特征两类技术。在介绍这类技术基本原理的基础上,对比分析了国内外代表性工作的能力现状。最后对超宽带雷达人体行为感知领域的后续重点研究方向进行了展望。Human target sensing technology with Ultra-WideBand(UWB)radar studies mainly how to recognize the position,behavior and intention of the human target according to the electromagnetic scattering echoes.It is an efficient complement to the optical-based target sensing,and can be applied to many scenarios such as the scenarios without light,the scenarios with occlusion,and the non-line-of-sight scenarios.Two key human sensing technologies are presented in this paper,i.e.,the spatial location-based method and the micro-Doppler-based method,and the relevant literatures about the two technologies are summarized.Finally,The future research directions of the UWB radar-based human target sensing filed are discussed in the conclusion.
