Abstract

Underwater radiated noise is one of several factors used to evaluate acoustic stealth performance. As the noise levels of naval vessels have been decreasing recently, there have been attempts to replace traditional underwater radiated noise measurement systems with array systems. This paper addresses the issue of measuring underwater radiated noise using a vertical line array system. By employing an array system, not only can array gain be achieved, but the application of a null steering algorithm further aims to reduce the impact of interference signals such as surface-reflected waves. A sea trial was conducted to analyze the performance, and the results demonstrated that using a null steering algorithm with an array consisting of 13 receivers yielded a gain of approximately 7 dB ~ 8 dB, including the array gain, compared to using a single hydrophone.

수중 방사 소음은 음향 스텔스 성능을 평가하는 여러 요소 가운데 하나이다. 최근 함정의 소음 준위가 점점 낮아지면서 기존의 수중 방사 소음 측정 시스템을 대신하여 배열 시스템을 적용하려는 시도가 있어 왔다. 이 논문에서는 수직 선배열 시스템을 이용하여 수중 방사 소음을 측정하는 문제를 다루었다. 배열 시스템을 사용함으로써 배열 이득을 얻을 뿐만 아니라 추가적으로 널 조향 알고리즘을 적용함으로써 해수면 반사파와 같은 간섭 신호의 영향을 감소시키고자 하였다. 성능을 분석하기 위한 해상실험이 수행되었으며, 실험 결과에서 단일 수중 청음기를 사용한 경우보다 13개의 수신기들로 구성된 배열에 널 조향 알고리즘을 사용한 경우 배열 이득을 포함하여 약 7 dB ~ 8 dB 정도의 이득을 얻을 수 있음을 보였다.
