Abstract
A non-contact method of physiological characteristic detection is provided to reduce the time consumption and complexity in calculation. The method includes transmitting a radar signal to at least one detected object through radar to obtain a reflected signal lasting for at least one time session, setting an estimated frequency for each of the at least one time session, obtaining a wave energy corresponding to the estimated frequency, and converging the wave energy with respect to the reflected signal through an optimized algorithm to obtain a physiological characteristic of the at least one detected object.
