DSP embeded hardware for non-contact bio-radar heart and respiration rate monitoring system

摘要

In this paper, we designed embedded-type noncontact bio-radar heart and respiration rate monitoring system. We implemented the hardware for arctangent combining, filtering and rate finding algorithm into the embedded system. We tested the hardware and compared it with the reference ECG measurements. Obtained results agree well with the ECG measurements. We propose arctangent demodulation for quadrature channel combining. Using Texas Instrument C6000 series DSP and external 12 Bit ADC, we implemented elliptic digital filter and detection algorithm for robust commercial hand held device.
