Abstract

어뢰 개발 단계에서는 어뢰의 성능 예측과 운용 방법 습득을 위해 효과도 분석이 실시되고 있다. 이 때 신뢰성 있는 데이터를 획득하기 위해서는 전술 상황을 실제에 가깝게 모델링한 시뮬레이션 프로그램이 필요하다. 경어뢰의 경우 잠수함을 주요표적으로 삼고 있는데, 잠수함의 어뢰 대항 수단인 회피 기동이나 어뢰음향대항체계(TACM)를 상세히 모델링해야 신뢰성 있는 효과도 분석 결과를 획득할 수 있다. 본 논문에서는 잠수함의 운동 특성을 반영하여 회피기동을 모델링하였으며 부유식 기만기, 자항식 기만기, 재머(jammer) 등 다양한 음향대항체계를 고려하여 잠수함 표적을 모델링하였다. 그리고 이러한 모델링을 통해 개발한 시뮬레이션 프로그램을 이용하여 경어뢰의 효과도를 측정하고 분석하였다. In the development phase of a torpedo, the effectiveness analysis is carried out to predict the performance and to learn how to use the torpedo. In order to obtain reliable data, it is required to model the tactical situation closely to the actual one. Because the submarine is a target of a lightweight torpedo, the anti-torpedo countermeasures of a submarine such as evasive maneuvering and TACM (Torpedo Acoustic Counter Measure) should be modeled in detail. In this paper, the evasive maneuvering is modeled reflecting the movement characteristics of the submarine. Furthermore various TACMs such as a floating-type decoy, a self-propelled decoy and jammers are also modeled. Then, effectiveness of a lightweight torpedo is measured and analyzed using the simulation program which is developed through the above modeling procedure.
