    Summary
    Non-contact vital sign detection based on Doppler radar systems presents several advantages in bio-medical and healthcare applications. Many research efforts have been proposed in this field to obtain accuracy and effectiveness for reliable wireless bio-signal detection. However front-end architectures, demodulation algorithms and signal processing methods can be further improved to retrieve the heartbeat and respiration spectra. In this work, based on existing millimeter wave systems, a continuous wave Doppler radar sensor operating at 60GHz was designed and implemented utilizing a low-IF receiver architecture to accurately detect heartbeat and respiration rate of a human target. In order to achieve robustness in addition to effectiveness, the sensor is integrated on a miniaturized single-board and the components power consumption is low. Potential other applications for this radar system will also be discussed.
