A number of front-end architectures, detection methods, and system-level integrations have been reported to improve the detection accuracy and enhance the system robustness. The advantages of noncontact vital sign detection draw lots of attention in various applications, such as health-care monitoring and rescue searching. Several portable systems and integrated circuits have been demonstrated recently. Different system architectures, baseband signal processing, system-level integration and potential applications are compared. Integrating the radar chip to achieve compact size, lower power consumption with signal processing techniques to increase the detection accuracy will continuously be the focus for the researchers in the future. ? 2014 IEEE.[SDGs]SDG3Radar equipment; Sensor networks; Signal processing; heartbeat; Non-contact detection; Radar sensors; respiration; Vital sign; Integrated circuitsconference paper10.1109/WiSNet.2014.68254992-s2.0-84903585342https://www.scopus.com/inward/record.uri?eid=2-s2.0-84903585342&doi=10.1109%2fWiSNet.2014.6825499&partnerID=40&md5=53baf9b747da88a677b9dc5ffbfaed4c
