Abstract

The present invention provides a physiological signal sensing radar with a DC compensation circuit, which comprises: a sensing radar and a DC compensation circuit. The sensing radar transmits a signal to an object to be tested. The object to be tested generates a set of coherent signals with physiological signal based on the signal. Then the coherent signal is amplified and down-converted by the sensing radar to extract the physiological signal for forming an output signal. The DC compensation circuit is electrically connected to the sensing radar, and has a boosting circuit and a buck circuit. The boosting circuit and buck circuit can properly adjust the voltage feedback to the radar to adjust the bias voltage between the positive and negative electrodes of the output signal according to the DC level shift generated by the reflected signal automatically, so that the DC level balance is not shifted.
