Abstract

Security solutions using fiber-optic cable have not yet secured a solid technical stability, through which the Acoustic detection security system also did not have a complete defense techniques such as false alarm and detecting fail due to a number of variables. In this paper, we investigate 4 characteristics for the channel of underwater acoustic communication. We also construct detection system as a construction method for security system using optical cable through the analysis of acoustic signal in underwater. We perform analysis of signal characteristics and noise of underwater optical cable, and then we confirms the possibility of real application.

광케이블을 이용한 보안 솔루션의 기술들은 아직까지 확실한 기술적 안정성을 확보하지 못한 상태이며, 그중 음향 감지를 통한 보안 시스템 역시 여러 가지 변수에 따른 오 경보 및 감지 실패 등의 완벽한 방어 기술을 확보하지 못한 상태이다. 본 논문에서는 수중 음향 통신의 수중 음향통신 채널에 대한 4가지 특성을 조사한다. 또한 수중에서 음향 신호 분석을 통한 광케이블을 이용한 감지 시스템 구축 방안으로서 감지 시스템을 구축한다. 또한 해저 광케이블의 신호 특성 분석과 잡음 분석을 수행한 후 이를 실제 적용 가능성을 확인한다.
