Breathing and Heartrate Monitoring System using IR-UWB Radar

This paper provides a feasibility study of estimating the heartrate and the breathing rate, using the waveform spectrum recorded by impulse radio ultra wideband (IR-UWB) radar. An algorithm is proposed that helps to separate the heartrate signal from the breathing signal. Furthermore, a Kalman filter is introduced that helps to reduce the noise factor from the obtained waveforms. The simulation result shows that the proposed algorithm can effectively estimate the breathing rate up to 97-99% and the heartrate above 90 % accuracy as compared to the traditional clinical equipment such as electrocardiograph (ECG)
