| description | 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.
FMCW 레이더에서의 누설 신호 감쇄 방법 및 그 레이더 시스템이 개시된다. 본 발명의 일 실시예에 따른 누설 신호 감쇄 방법은 레이더 시스템에서의 누설 신호 감쇄 방법에 있어서, 비트 신호에 대한 동위상 신호와 직교위상 신호를 생성하는 단계; 상기 동위상 신호와 직교위상 신호를 이용하여 복소 신호를 생성하는 단계; 상기 복소 신호에 포함된 상기 누설 신호의 위상 노이즈를 정류점에 집중시키는 단계; 및 상기 위상 노이즈의 정류점 집중에 기초하여 상기 위상 노이즈를 감쇄시키는 단계를 포함한다. |
