Can ultra wideband (UWB) impulse radar accurately detect human heart rate through a wall?
UWB impulse radar combined with principal component analysis can accurately detect human heart rate through walls, offering potential for noncontact healthcare and surveillance.
Offers proof-of-concept for noncontact, through-wall vital sign monitoring; leaves open clinical.
Measuring the physiological functions of the human body in a noncontact manner through walls is useful for healthcare, security, and surveillance. And radar technology can be used for this purpose. In this paper, a new method for detecting the human heartbeat using ultra wideband (UWB) impulse radar, which has advantages of low power consumption and harmlessness to human body, is proposed. The heart rate is extracted by processing the radar signal in the time domain and then using a principal component analysis of the time series data to indicate the phase variations that are caused by heartbeats. The experimental results show that a highly accurate detection of heart rate is possible with this method.
