24 GHz Radar Heart Rate Variability (HRV) Estimation Using Wavelet Transform
摘要
Heart Rate Variability (HRV) is normally detected and extracted from the Electrocardiogram (ECG) and is a significant index of a human body status. The ECG normally use invasive skin contact sensors. A new non-invasive approach of extracting HRV based on wavelet transform from heart movement acquisition method using a 24 GHz radar sensor is presented. An ECG and radar heart movement joint database from 30 subjects is used in this study to validate the performance of the extraction algorithm. It is shown that the proposed radar recording processing method has a consistent performance in locating heart rate, showing the direct link between radar beats and associated ECG dataset R peaks.
