Zusammenfassung:	Disclosed are a leak signal attenuation method in an FMCW radar and a radar system thereof. According to one embodiment of the present invention, the leak signal attenuation method in a radar system comprises the steps of: generating an in-phase signal and a quadrature phase signal for a bit signal; generating a complex signal using the in-phase signal and the quadrature phase signal; concentrating phase noise of a leakage signal included in the complex signal at a rectification point; and attenuating the phase noise based on the rectification point concentration of the phase noise.
