Abstract: Various examples are provided for accurate heart rate measurement. In one example, a method includes determining respiration displacement from radar-measured cardiorespiratory motion data; adjusting notch depths of a data filter based upon the respiration displacement; and identifying a heart rate from data filtered by the data filter. In another example, a system includes a computing device that can determine a respiration displacement from radar-measured cardiorespiratory motion data; wherein the computing device can adjust a data filter based upon the respiration displacement; and can identify a heart rate based on data filtered by the data filter.
