최근 전장환경의 급격한 변화와 고도화된 과학기술로 인해 무기체계의 성능은 매우 발전되었으며 세계 각국은 고성능, 고효율의 최신 무기체계 개발에 역량을 집중하고 있다. 개별 무기체계에 대응하여 새롭게 개발된 무기체계는 기존 무기체계에 대한 패러다임을 뛰어넘어 새로운 개념과 운용방식을 요구하고 있다. 무기체계의 효과를 규명하고 검증하기 위한 수단으로 가장 적합한 것은 실제전장에 무기체계를 투입한 실기동 실험을 통해 효과를 분석하는 것이다. 그러나 무기체계 효과분석을 위해 실기동훈련을 계획하고 실시하는 것은 비용 뿐 아니라 군사력 동원면에 있어서 비효율적이고 부담이 높은 단점이 있으므로, 국방시뮬레이션 기술을 활용하여 저비용 고효율의 모의분석을 실시함으로써 계량적인 효과분석을 수행하고 수치화된 판단 근거를 제공하는 것이 보다 바람직하다고 할 수 있다. 본 고는 대대급 이하 소부대의 전장상황에서 지상군 단위무기체계의 효과 분석을 수행할 수 있는 국방 시뮬레이션 모형의 개발 방향을 제시한다.

This paper analyses the effectiveness of Kill Chain (KC) and Korea Air and Missile Defense (KAMD), also known as the K2 systems, using monte carlo simulation. It is assumed that the K2 systems are consisted with unitary KC and multi-layered (upper-tier and lower-tier) KAMD. And each system has two or three arbitrary weapon systems and its combination makes 12 scenarios. Measures of effectiveness (MOE) of the K2 systems were defined as ratio of eliminated ballistic missiles from total threats. And total cost was calculated by number of weapon launched and its unit cost. MOE and total cost of the K2 systems were estimated using monte carlo simulation with a thousand iteration for each scenario. Cost-effectiveness analysis was performed and the best candidate was selected using fixed effectiveness approach. As a result, the performances of KC are prime factor that affects both effectiveness and total cost of the K2 systems. It is also, acquired proper level of lower-tier KAMD to achieve desired defense effectiveness. For future work, it needs to be performed cost-effectiveness analysis based on practical specification and life cycle cost of weapon systems.

Directed energy weapon enables to radiate the concentrated energy so as to result in distraction and overload of the target electronics. Analysis on effectiveness of weapon system can be important consideration in order to determine performance and design weapon system. In this paper, air defense weapon system, which is one of directed energy weapon system is studied. In order to analyze the effectiveness, the reflector antenna with high power circularly polarized horn antenna is designed, and power density in axial effective area is simulated and calculated using Friis formula. Through the study, the validity of antenna system is verified, and the effectiveness of directed energy weapon system on the target is evaluated.

워게임 모형을 이용하여 다양한 전장환경과 부대편제하에서 전투모의를 실시함으로써 개별 무기체계가 전투효율에 미치는 정도를 판단할 수 있다. 워게임은 부대간의 상호작용과 무기체계 효과, 전투력수준간의 비선형적인 요소들을 반영할 수 있다. 또한 모의 분석결과는 무기체계의 비용대 효과분석 및 소요 산출과 운영개념 정립 등에 활용될 수 있다. 특히, JANUS 모형은 개별 무기체계에 대한 상세한 특성자료를 반영하고 수십 미터 단위의 해상도를 갖는 수치지형자료를 사용할 뿐만 아니라, 세밀한 전투모의 논리로 구성되어 있기 때문에 지상 무기체계의 효과 분석에 매우 적합하다. 본 고에서는 JANUS 모형의 일반적인 특징과 모형 운용을 위해 필요한 입출력 자료를 소개하고 전투효율 분석 방법에 대해 설명하고자 한다.

Modeling and Simulation techniques are useful to construct executable battlefields and forces on computers, and have been utilized to analyze effectiveness of weapon systems in the computerized war environment. However, most weapon simulations so far have exhibited low reusability and extensibility, since they have been developed for specific simulation objectives with different structures and simulation engines. In this paper, we identify requirements for defense modeling and simulation activities and propose a simulation engine to support the identified requirements. We define the software architecture of the proposed engine, in a way to efficiently provide usability, component-based reusability, interoperability, and reuse-based development.

An integrated simulation engine provides tools, services, and standards to support various activities in the entire M&S from modeling and simulation to analysis of the simulation results. Many countries have developed integrated simulation engines to efficiently assist complex M&S activities. However, we do not have domestic simulation engines especially designed for defense M&S, therefore, developing M&S softwares still remains as a hard task with high cost and tine. OpenSIM(Open Simulation engine for Interoperable Models) is an integrated simulation engine and provides tools, services and standard interfaces for weapons analysis. OpenSIM's services are comprised of classes, member functions and data attributes which are commonly used in modeling, simulating and analyzing weapons systems. In this paper, we introduce OpenSIM's services in C++ APIs and illustrate them through an ASM example(Air to Surface Missile).

The simulation-based weapon system effectiveness analysis is to support the decision making in the acquisition process of the defense domain. The effectiveness of the weapon system is a complexly influenced indicator from various factors such as environment, doctrine and so on. And the measurement of effectiveness can be defined differently in compliance with major issues in the weapon system. Because of this, the weapon system effectiveness analysis requires the comparative experiment of various alternatives based on the underlying assumption. This paper presents the efficient approach to reconfigure the simulation using the reflection technique. The proposed method contains the recoupling and resetting the simulation entity using DEVS(Discrete EVent System specification) formalism-based dynamic plug-in method. With the proposed method, this paper designs the effectiveness analysis environment that can efficiently handle the various alternatives of the weapon system.

Defense M&S for weapons effectiveness is a realistic way to support virtual warfare similar to real warfare. As the war paradigm becomes platform-centric to network-centric, people try to utilize smartphones as the source of sensor, and command/control data in the simulation-based weapons effectiveness analysis. However, there have been limited researches on integrating smartphones into the weapon simulators, partly due to high modeling cost - modeling cost to accomodate client-server architecture, and re-engineering cost to adapt the simulator on various devices and platforms -, lack of efficient mechanisms to exchange large amount of simulation data, and low-level of security. In this paper, we design and implement Smartphone Adaptor to utilize smartphones for the simulationbased weapons effectiveness analysis. Smartphone Adaptor automatically sends sensor information, GPS and motion data of a client's smartphone to a simulator and receives simulation results from the simulator on the server. Also, we make it possible for data to be transferred safely and quickly through JSON and SEED. Smartphone Adaptor is applied to OpenSIM (Open simulation engine for Interoperable Models) which is an integrated simulation environment for weapons effectiveness analysis, under development of our research team. In this paper, we will show Smartphone Adaptor can be used effectively in constructing a Live simulation, with an example of a chemical simulator.
