Abstract

The application of non-contact radar to monitor the parameters of human vital has become a topic of concern to many researchers in recent years, but the vital signals collected in the monitoring process can always contain interferences. This paper proposes a method to deal with the separable interferences with the original signal in the time domain or frequency domain: after the contaminated segment is cut off, the contaminated segment is reconstructed by using the estimation results of the non-contaminated segment, and iterative processing is performed to improve the accuracy of estimation of human respiratory rate and heart rate. The results of numerical simulation and measured data processing show that the proposed algorithm can effectively improve the accuracy of human respiration rate and heart rate estimation compared with the direct clipping of contaminated segments.
