一种基于连续波生物雷达的人体步态非接触检测系统
A New Approach for Human Gait Non-contact Detecting System Based on Continuous-wave Bio-radar
摘要
Abstract
Human gait is a complex mechanism by which a variety of muscles and bones must work together in precise coordination to create characteristic human locomotion, which can be used as an identiifcation or clinical gait characterization for detecting pathological conditions. This article introduced a non-contact detecting system for human gait based on continuous-wave bio-radar. Through spectrum analysis of the radar echo signal generated during human walking, main frequency of the human gait signal was extracted. Correlation analyses were made with the data obtained from the acceleration sensor. Experimental results show that the bio-radar can detect the gait signal of human walking without contact, and has good consistency with the results of acceleration and video monitoring.关键词
