DEVICE AND METHOD FOR MEASURING BIOLOGICAL SIGNAL OF NONCONTACT

摘要

PURPOSE: An apparatus for measuring a contactless organism signal and a method for measuring a contactless organism signal are provided to block the interference of the respiratory rate signal of a base band. CONSTITUTION: A Doppler radar unit(110) measures the bio signal of an electric wave which is reflected according to the movement of an organ. The Doppler radar unit changes a measured bio-signal into a high frequency signal and transmits the signal. A digital signal processing unit(120) changes a received high frequency signal into a digital signal. The digital signal processing unit determines the number of the heart rate and the respiratory rate of a user by performing frequency domain analysis. A display unit(130) displays the measured bio-signal and the result analyzed in the digital signal processing unit.
