Zusammenfassung:	According to the present invention, disclosed are a method for detecting a narrowband low frequency and a system thereof. The method for detecting a narrowband low frequency includes a process of automatically adjusting contrast and brightness to form a gram (image) during a process of obtaining low frequency analysis and recording (LOFAR) image information using a sonar signal as input, automatically provides an image suitable for the vision of an operator without intervention of the operator, increases target detection performance by being automatically operated, and is capable of continuously providing high quality data having a good signal-to-noise ratio without disconnection. 본 발명에 따르면, 소나 신호를 입력으로 하여 저주파 분석 및 기록(LOFAR) 영상 정보를 얻는 과정 중에 그램(영상)을 형성하기 위해 대비 및 밝기를 자동으로 조절하는 과정을 포함하며, 운용자의 개입 없이 자동적으로 운용자의 시각에 적합한 영상을 제공할 수 있으며, 자동으로 조작되어 표적탐지 성능이 향상되며, 신호 대 잡음비가 좋은 양질의 데이터를 끊김 없이 지속적으로 제공할 수 있는 협대역 저주파 탐지방법 및 시스템이 개시된다.
