基于毫米波雷达的心率变异性检测方法
Heart Rate Variability Detection Method Based on Millimeter Wave Radar
摘要
Abstract
Heart rate variability(HRV)is an important indicator for evaluating cardiovascular function and autonomic nervous system status.Accurately estimating HRV with millimeter wave radar is a research hotspot in the field of non-contact vital sign detection.Therefore,a HRV detection algorithm based on millimeter wave radar is proposed.Firstly,the frequency modulated continuous wave radar echo signal is preprocessed and the signal is denoised and reconstructed with singular spectrum analysis.Then,the variational mode decomposition algorithm based on modal selection criteria is adopted to adaptively extract the heartbeat signal and calculate the heart rate.Finally,by detecting the peak value of the heartbeat signal,the specific time of the heartbeat is estimated,and the inter-beat interval is obtained to calculate the time-frequency domain characteristics of HRV.The experimental results show that this method has high accuracy and robustness in HRV estimation.关键词
