Abstract:

Objective  This study aimed to separate the breathing and heartbeat signal effectively from the biological radar echo signal,as well as extract the breathing and heartbeat characteristics in order to provide the basis for clinical diagnosis and disease prevention.Methods  Analysis the characteristics of the radar echo signal,use the combined harmonic of the breathing signal as a reference input signal of the adaptive filter to improve the algorithm.Related experiments were designed and completed.Results  This paper presents a separation algorithm of heartbeat and respiration based on LMS adaptive harmonic cancellation.Conclusion  The output results suggest that the results of simulated household monitoring experiments were quite well.
