雷达微多普勒信号可用于安全应用,如在机场、发电厂等地检测和评估人类活动。微多普勒信号反映身体各个部位的运动。使用77 GHz雷达,我们获得了一个或两个人的人体微多普勒信号,这些人有不同的运动方式,不同的运动方向,以及没有或有携带物体。我们分析了这些情况下的微多普勒特征,并观察了特征的一般性质。我们进一步建议在设计人类目标的检测器和分类器时使用的属性。
Radar micro-Doppler signatures can be utilized for security applications like detection and assessment of human activity at airports, power plants etc. The micro-Doppler signature reflects the movement of various body parts. Using a 77 GHz radar we have obtained human micro-Doppler signatures of one or two persons, with different ways of movement, different movement directions and without or with carrying objects. We have analyzed the micro-Doppler signatures for these cases and we observe general properties of the signatures. We further suggest properties to use when designing detectors and classifiers of human targets.
