  • 유도탄에 의존하는 전투 경향은 향후 계속적으로 증대될 것이며 더구나 유도탄은 지금까지 설명한 것 같이 장거리화, 고속화, 스텔스화, 고고도 또는 저고도 탄도선택, 명중 직전까지 탐지 곤란 및 최종유도 단계에서 고가속도 운동 등 성능은 향상 일로에 있습니다. 함정의 생존성을 제고시키기 위한 각국의 대함유도탄 방어체계 개발 노력은 함정 탑재 무기체계인 근접방어 무기체계, 함대공유도탄, ESM 및 유도탄 기만 장치의 지속적인 성능개량과 함께 지속될 것입니다

  • Naval combat system is total management system integrating a ship and several weapon system functions. For the mission of a ship, naval combat system manages features and constraints of each weapon system. Proper treats of each weapon system's conditions guarantee effective performances of naval combat system. In this paper, the relationship of anti-air weapon system's on board position and self-defence effectiveness against anti-surface missiles is studied

  • CEC, 근접방어무기체계, 지휘통제체계 등에 사용되는 위협평가시스템은 자동위협평가, 방어구역 위협지수, 무기할당 등의 공통된 기능을 포함하고 있고, 시스템 환경의 변화 또는 성능 향상에 따라 수시로 업그레이드가 요구된다. 따라서 본 논문에서는 생산성 향상과 중복투자 방지로 인한 비용감소 효과를 거둘 수 있는 제품계열 방법론을 위협평가시스템 개발에 적용하는 방안을 제안한다. 위협평가시스템의 제품계열 방법론 적용을 위해 핵심자산 개발 프로세스를 수행하여 제품계열 영역지정, 핵심자산, 제품계획을 정의한다. 제품계열 영역지정은 Feature 모델링을 이용하여 공통점과 차이점을 식별하고, 핵심자산은 아키텍처 설계 중심으로, 그리고 각 핵심자산의 부착 프로세스를 종합하여 제품계획을 수립한다.

  • It is crucial to set up early the required performance of surface ship for preventing the risk factors such as an excess of performance, cost and period in development stage. In this study, MOP and MOE are proposed to establish the method for deriving alternatives, MOP represents the defensive effect for anti ship missiles and MOE is the ratio of cost and performance. The 16 engagement scenarios which selectively install RF decoy, RF jammer, CIWS and anti air missile are suggested. The simulation results by using NORAM tool operated by ROK Navy show that the ship survivability is 0.605~0.975 and MOP is 0.301~0.887. The analyzed results represent the operating scenario with RF decoy, RF jammer and short range anti air missile is the best cost and effectiveness measure.

  • In this paper, the optimal evasive maneuver strategies for typical subsonic ASM(anti-ship missile) to reach its target ship with high survivability against CIWS(close in weapon system) are studied. The optimal evasive maneuver input is defined by the homing command optimizing the cost function which takes aiming errors of CIWS into account. The optimization problem for the effective evasive maneuver is formulated based on a simple missile dynamics model and a CIWS model. By means of solving the problem, a multiple hypotheses testing method is proposed. Since this method requires generation of too many hypotheses, the hypothesis-pruning technique is adopted. The solution shows that the optimal evasive maneuver is a bang-bane shaped command whose frequency is varied by the aimpoint determination strategy in CIWS.

  • In this paper, the combat effectiveness of ship guidance rockets to counter the threat of multiple USV(Unmanned Surface Vehicle) was analyzed in three cases. The probability of sinking a number of USVs approaching by distance was compared using various weapon systems and guided rocket systems installed on the naval vessels. As a result of the analysis, it was found that the combat effectiveness of the guided rocket was improved compared to the close defense system of the anti-ship missile installed on the naval vessels.
