Abstract
A vital-sign radar sensor uses wireless internet signals to detect vital signs. It includes a first and second demodulation unit to demodulate an incident and reflected wireless internet signal with an injection-locked oscillator into a first and second demodulated signal, respectively. The combined use of the first and second demodulated signals can eliminate the influence of communication modulation on the extraction process of a Doppler shift due to vital signs. Moreover, the vital-sign radar sensor is a receive-only device so that it won't cause interference to ambient wireless communication networks.
