Abstract

This paper aims to evaluate the acoustic detection performance for the deployment of the source and receiver positions of a bi-static sonar. In contrast with a mono-static sonar, a bi-static sonar has a large amount of computation and complexity for deployment. Therefore, in this study, we propose an assessment method that reduces the amount of computation while considering the variability of the ocean environment as a method to apply to the placement of the source and receiver of a bi-static sonar. First, we assume the representative ocean environment in the shallow and deep water. The signal excess is calculated with the source to receiver ranges and sensor depths. And the result is compared with the proposed assessment method of acoustic detection performance.

본 논문은 양상태 소나의 음원과 수신기 배치를 위해 음향탐지성능을 평가하는 것을 목표로 한다. 단상태 소나와는 다르게 양상태 소나의 경우에는 배치를 위한 연산량과 복잡도가 크기 때문에 해양환경을 고려한 배치 연구는 진행된 바가 없다. 따라서 본 연구에서는 양상태 소나의 음원과 수신기 배치에 적용하기 위한 방법으로 해양환경의 변동성을 고려하면서도 연산량을 줄이는 평가 방법에 대해 제안한다. 본 연구에서는 천해와 심해의 대표 해양환경을 선정하였으며, 그 해역에서 음원과 수신기 간의 거리 및 센서 심도를 변경하며 신호초과를 계산하고, 그 결과를 제안하는 음향탐지성능 평가 방법과 비교 및 분석한다.
