Microwave Doppler Radar for Heart Beat Detection Versus Electrocardiogram
This paper provides a validation approach for a microwave Doppler Radar system used for heartbeat detection. The proposed system is tested at 16 GHz with several transmitted power, simultaneously with a pc-based electrocardiogram. Obtained results show accurate detection for the heartbeat signal in terms of heartbeat rate and heart rate variability.
متن کاملHarmonics Cancellation in Noncontact Microwave Doppler Radar Cardiopulmonary Sensing
This paper addresses the challenge of respiration harmonics cancellation in microwave Doppler radar cardiopulmonary sensing. A new signal processor based on adaptive noise cancellation is proposed. When the heartbeat signal is easily overwhelmed by the respiration harmonics, the traditional band-pass filters are used to separate heartbeat signal from the respiration signal, then the LMS-based m...

متن کاملSoftware Defined Doppler Radar as a Contactless Multipurpose Microwave Sensor for Vibrations Monitoring
A vibration sensor based on the use of a Software-Defined Radio (SDR) platform is adopted in this work to provide a contactless and multipurpose solution for low-cost real-time vibrations monitoring. In order to test the vibration detection ability of the proposed non-contact method, a 1 GHz Doppler radar sensor is simulated and successfully assessed on targets at various distances, with variou...
متن کاملReal-Time Through-Wall Situation Awareness Using a Microwave Doppler Radar Sensor
This paper deals with the development of a short-range radar suitable for the detection of humans behind visually opaque structures such as building walls. The system consists in a continuous wave Doppler radar operating in the S-band of the electromagnetic spectrum in order to ensure an adequate signal penetration through the walls. Based on the interaction of the electromagnetic waves with hu...
