Zusammenfassung:The present invention relates to a method to remove a noise tone in a digital area of a synthetic aperture radar receiver, a synthetic aperture radar receiver and a computer-readable recording medium for the same. A method to remove a noise tone in a digital domain of a synthetic aperture radar receiver using a deramping structure according to an embodiment of the present invention comprises: (a) a step of extracting a noise tone location of a deramped image signal; (b) a step of selecting a noise tone of the noise tone extracted by step (a) to be removed; and (c) a step of removing the noise tone selected by the (b) step from raw data. 본 발명은 영상 레이더 수신기의 디지털 영역에서의 잡음 톤 제거 방법, 이를 위한 영상 레이더 수신기 및 프로그램 기록매체에 관한 것이다. 본 발명의 일 실시예에 따른 디램핑 구조를 사용하는 영상 레이더 수신기의 디지털 영역에서의 잡음 톤 제거방법은 (a)디램핑된 영상 신호의 잡음 톤 위치를 추출하는 과정과; (b)상기 (a)과정에 의해 추출된 잡음 톤 중에서 제거할 잡음 톤을 선택하는 과정과; (c)상기 (b)과정에 의해 선택된 잡음 톤을 원시데이터에서 제거하는 과정을 포함하는 것을 특징으로 한다.
