dc.description.abstract소나를 이용한 수중 표적 탐지를 위해서는 해양환경 및 소나 특성이 반영된 탐지성능 분석이 수행되어야한다. 수동 및 단상태 소나의 탐지성능 모델링은 해양환경을 고려하더라도 비교적 신속하게 수행될 수 있다. 하지만양상태 및 다중상태 소나의 경우 수동 및 단상태 소나에 비해 계산 측면에서 높은 복잡성과 연산량이 요구되기 때문에국내외에서는 음속구조나 해저지형과 같은 해양환경을 고려하지 않거나 단순화된 형태로 양상태 및 다중상태 탐지성능 분석이 수행되고 있다. 따라서 본 연구에서는 동해 울릉분지 해역에서의 음파전달 특성 분석을 통해 잔향음과 해양환경이 양상태 탐지성능에 미치는 영향을 분석하였다. 수평 방위 해상도 변화 및 소음제한환경 가정 여부에 따른 탐지성능 모델링을 수행하였다. 이로부터 소나운용 수심이 최소음속층에 가까워질수록 해저지형의 영향이 줄어들며 잔향음 제한환경은 비교적 근거리에서만 형성된다는 것을 관찰하였다. 이러한 경향은 단순화하여 계산한 탐지성능 모델링의 결과와 정교하게 계산된 양상태 탐지성능 모델링 결과의 비교를 통해서도 확인 가능하였다.-
dc.description.abstractTo detect underwater targets using sonar, sonar performance analysis that reflects the ocean environment and sonar characteristics must be performed. Sonar performance modeling of passive and monostatic sonar can be performed relatively quickly even considering the ocean environment. However, since bistatic and multistatic sonar performance modeling require higher computational complexity and much more time than passive or monostatic sonar cases, they have been performed by simplifying or not considering the ocean environment. In this study, the effects of reverberation and ocean environment in bistatic sonar performance were analyzed using the bistatic reverberation modeling in the Ulleung Basin of the East Sea. As the sonar operation depth approaches the sound channel axis, the influence of the bathymetry on sound propagation is reduced, and the reverberation limited environment is formed only at short distances. Finally, it was confirmed that similar trends appeared through comparison between the simplified and elaborately calculated sonar performance modeling results.-
