Since a homing torpedo system consists of various subsystems, organic interactions of which dictate the performance of the torpedo system, it is necessary to estimate the effects of individual subsystems in order to obtain an optimized design of the overall system. This paper attempts to gain some insight into the detection mechanism of a torpedo run, and analyze the relative importance of various parameters of a torpedo system. A database for the analysis was generated using a simulation model based on the combined discrete event and discrete time architecture. Multiple search schemes, including the snake-search method, were applied to the torpedo model, and some parameters of the torpedo were found to be stochastic. We then analyzed the effectiveness of torpedo’s detection capability according to the torpedo speed, the target speed, and the maximum detection range.

적 잠수함을 탐지했을 때 적 잠수함이 10km 이내의 거리에서는 어뢰에 부착된 선체 부착형 능동소나로 적 잠수함을 추적하여 직접 공격하는 방법이 효과적이다. 그러나 10km에서 19km 정도의 거리인 경우에는 로켓트를 이용하여 어뢰를 목표지점까지 운반하고 운반된 어뢰가 바닷속에 착수하면 수동예인 음탕기(TASS)로 적 잠수함을 탐지 추적하는 체계가 효율적이다. 19km 이상이 되면 헬기로 적 잠수함을 탐지하고 목표지점에 어뢰를 투하시키는 방안이 일반적으로 운용되고 있다. 그러나 최근에는 50km 정도까지도 유도탄으로 어뢰를 운반하는 체계가 선호되어 적용되고 있기도 하다.

적의 어뢰공격을 받을 때 기만기로 방어하는 것은 대단히 유효한 수단이며, 최신 기만시스템은 어뢰의 유도장치에 대응하는 여러가지 기능을 구비하여 함정과 유사한 신호를 발생시켜 어뢰를 함정으로부터 다른 방향으로 유도해서 추적을 차단시킵니다.

잠수함과 어뢰의 추진기는 고속화와 정숙화라는 동시 만족이 어려운 2가지 요구조건을 만족시키기 위하여 설계, 이론, 해석, 소재, 제작기술 등 전 분야에서 종합적으로 연구 개발되어져 왔습니다. 현재까지도 잠수함에는 저소음화된 추진기, 어뢰에는 반전추진기가 주로 사용되고 있으나 잠수함, 어뢰의 고속화 추세로 볼때 미국, 영국 등에서 적용을 시작한 펌프제트는 관련기술이 계속 발전되어 기존의 추진기를 대신하게 될 것입니다

We consider simulation study combining static and mobile decoys for survivability of a surface warship against torpedo attack. It is assumed that an enemy torpedo is a passive acoustic homing torpedo and detects a target within its maximum target detection range and search beam angle by computing signal excess via passive sonar equation, and a warship conducts an evasive maneuvering with deploying static and mobile decoys simultaneously to counteract a torpedo attack. Suggesting the four different decoy deployment plans to achieve the best plan, we analyze an effectiveness for a warship's survival probability through Monte Carlo simulation, given a certain experimental environment. Furthermore, changing the speed and the source level of decoys, the maximum torpedo detection range of warship, and the maximum target detection range of torpedo, we observe the corresponding survival probabilities, which can provide the operational capabilities of an underwater defense system.

세계각국에서는 어뢰방어체계에 관련된 모든 기술은 매우 신중히 보호하고 노출시키지 않고 있다. 어뢰방어체계 자체는 주문구매도 가능하나, 극비에 속하는 자국 함정의 음향특성을 제작국에 제시해야 되기 때문에 이 분야는 독자개발이 매우 바람직하다.

It is necessary for us to undergo trial and error for eliciting the rational requirement of the acquisition of weapon systems, but the M&S is general approach due to costs and risk of the development. In addition to the acquisition of weapon systems, M&S is extensively employed in the analysis and the training of developed weapon systems. The ADD (Agency for Defense Development) has developed DEVS integrated development environment (QUEST) that provides M&S general ground technique composed of simulation model implementation services, simulation result analysis services, and simulation interface services. This paper describes the interface architecture and the implementation of torpedo target detection section interface simulation system using QUEST. The torpedo target detection section interface simulation system is composed of torpedo target detection section which calculates a result of target detection and the QUEST scenario generator which provides simulation scenario for performance test of the torpedo target detection section. The interface architecture of torpedo target detection section interface simulation system is designed to verify the interface and performance of the torpedo target detection section by linking with the QUEST scenario generator.

HMS(Hull Mount Sonar) equipment mounted on PCC(Patrol Combat Corvette) is suitably designed for active mode, and the specific character of sensor or system is not appropriate for the frequency range to detect a torpedo. In this article, in order to implement the function of detecting torpedoes with HMS of existing PCC, I will analyze the feature of input signals each PCCs and design a circuit to compensate reversely for the input signal in certain frequency. And also, I will suggest the most adequate torpedo defense system suitable for the special operating environment and the characteristic of naval vessels, implementing functions such as AGC of input signal and fixing the frequency range of different input signals per different warships.
