Abstract

Narrow band signal estimation and broad band signal estimation can be used to detect the ship-radiated noise. The broad band signal estimation method to detect the ship-radiated noise is called DEMON (Detection of Envelop Modulation On Noise). This paper proposes a new DEMON algorithm using filter bank and autocorrelation. We show the proposed algorithm estimates the hidden period in the wide band signal better than the conventional DEMON algorithm and the recently proposed filter-bank based DEMON algorithm.

배의 방사 소음을 이용하여 배를 탐지하는 데는 협대역 톤을 추정하는 방법과 광대역 신호에 내포된 주기성 신호를 추정하는 방법이 있다. 그 중에서 광대역 신호에 내포된 주기성 신호를 추정하는 방법을 데몬 신호 처리법이라고 한다. 본 논문에서는 데몬 처리를 위해서 자기 상관기를 적용한 필터 뱅크를 기법을 제안한다. 그리고 합성된 신호와 실제 신호를 바탕으로 기존 방법들과 비교하여 기본 주파수 신호를 우수하게 추정할 뿐만 아니라 여러 고차 하모닉 성분들도 잘 추정하여 기본 주파수 추정의 신뢰성도 높일 수 있음을 보인다.
