Study of the Ballistocardiogram signal in non-contact life detection system based on radar
In this article,our study of non-contact method viaradar for monitoring the heart and respiratory rates of human subject is reported.The system is constructed which synchronously detects the lectrocardiogram signals by the electrocardiograph and the ballistocardiogram signals by the non-contact life parameter detecting technology.Also,the detected signals are analyzed respectively in the time and frequency domain.The results show that the cycle of the ballistocardiogram is obvious in time domain and that the rhythm of the two kinds of signals keeps consistent.And their characteristic points in frequency domain are also the same.The clinical medicine usefulness of ballistocardiogram detected by the non-contact technology is approved and the credible evidence for the succeeding signal analysis and the clinical application is provided.Furthermore,the characters of the heartbeat signal detected by our system and the reasons for that are also discussed in detail in our paper.
