A method for measuring a high-accuracy and real-time heart rate based on a continuous-wave radar is provided. The method includes receiving an in-phase (I) signal and a quadrature (Q) signal for a receive signal received through the continuous-wave radar, selecting any one signal by comparing magnitudes of the received I signal and the received Q signal, performing frequency transform of each of bases respectively having predetermined phases with respect to the any one selected signal, and determining a heart rate based on a magnitude response of each of the bases by the frequency transform.

Method for measuring high-accuracy realtime heart rate based on continuous-wave Doppler radar and radar system therefor

A method for mitigating a leakage signal in an FMCW radar and a radar system thereof are disclosed. The method for mitigating the leakage signal in the radar system includes generating an in-phase signal and a quadrature signal for a beat signal, generating a complex signal using the in-phase signal and the quadrature signal, concentrating a phase noise of the leakage signal included in the complex signal on a stationary point, and mitigating the phase noise based on stationary point concentration (SPC) of the phase noise.
