Abstract

Bistatic sonar performance varies significantly depending on the ocean environment, the location (latitude, longitude) and water depth of the source and receiver. Therefore, research on optimal deployment of bistatic sonar considering ocean environment is necessary. In this study, we suggest an algorithm to optimize the location and water depth of source and receiver when operating monostatic and bistatic sonar on two spatially separated surface ships in the Ulleung Basin in the East Sea. A particle swarm optimization algorithm was used to search the location and water depth of the source and receiver to maximize the detectable area within the search area. As a result of performing bistatic sonar deployment using the algorithm proposed in this study, the detectable area increased as the number of model iterations increased. Additionally, it was confirmed that the source and receiver on the two surface ships converged to the optimal location and water depth.

양상태 소나는 해양환경, 송·수신기의 위치(위도, 경도)와 수심에 따라 탐지성능이 크게 변동한다. 따라서 해양환경을 고려한 양상태 소나 최적 배치 연구가 필요하다. 본 연구에서는 동해 울릉분지 지역에서 공간적으로 분리된 수상함 2척에서 각각 단상태 소나와 양상태 소나를 운용하는 경우, 송·수신기의 위치와 수심을 최적 배치하는 알고리즘을 제안한다. 탐색구역 내 탐지가 가능한 면적을 최대화하는 송·수신기의 위치와 수심을 탐색하기 위해 입자 군집 최적화 알고리즘이 사용되었다. 본 연구에서 제안하는 알고리즘으로 배치를 수행한 결과, 모델 반복 횟수의 증가에 따라 탐지면적이 증가하였으며 수상함 2척의 송·수신기가 최적의 위치와 수심에 수렴하는 것이 확인되었다.
