In this paper, there is a research for providing environmental data to reflect environmental effects to the simulation for the aviation weapon systems by the construction of the synthetic battlefield. The results of the aviation engagement simulation are able to differ by environmental effect. This paper analyzes the real aviation battlefield and designs the synthetic battlefield based on the analysis. In order to construct the designed synthetic battlefield, we collects the real environmental data for the atmosphere and structures the collected data using GIS (Geographic information system interpolation). The main objective of this paper is to design the synthetic battlefield based on the derived environmental factors from the analysis of the real aviation battlefield, and it constructs the designed synthetic battlefield by the collection of real atmosphere data. The constructed synthetic battlefield provides the environmental data which are requested from the distributed simulation system, and it makes the system reflect environmental effects to the simulation.

'분산 모의훈련 전장환경'은 실제 또는 가상전쟁, 전투 등 군사 상황을 묘사하기 위해, 둘 또는 그 이상의 적대 세력간에 발생하는 군사적 상황을 게임규칙, 자료 및 절차를 사용하여 모의하는 군사작전 게임(war game)을 의미한다. 이는 컴퓨터와 네트워크를 이용한 '합성 가상 전장환경'에서 구현되는데, 특성상 다수의 게이머와 게이머, 게이머와 객체, 객체들간에 네트워크를 통한 빈번한 메시지 송.수신을 통한 정보를 교환하고 실시간으로 상호동작 한다. 즉, '합성 가상 전장환경'의 구현을 위해서는 신뢰성과 실시간성을 보장하는 다자간 통신의 보장이 핵심을 이룬다. 그러나, 일반 인터넷상의 브로드캐스팅 기술을 적용할 경우, 가상전장환경에서 폭주하는 통신량을 실시간으로 처리하기엔 어려운 문제점이 있다. 따라서 '합성 가상전장가상환경'의 보다 효과적인 구현을 위해서는 고신뢰 실시간 다중 그룹통신 기술의 개발이 요구된다. 본 논문은 그룹통신 개념에 기반하여 가상 합성 전장 환경에 적용할 수 있는 효율적인 전송 서비스를 위한 네 가지 전송 알고리즘을 제시하며, API 설계를 통해 서비스를 구현한다.

This paper proposes a framework to construct the synthetic battlefield based aviation engagement simulation model for the distributed system. The proposed framework has the synthetic battlefield in the HLA (High Level Architecture)/RTI (Run-Time Infrastructure) based distributed system to reflect environmental effects into the aviation engagement simulation model. In an aviation engagement, the environment affects weapon systems such as detection and movement. Therefore, environmental effects are required to be reflected in the simulation. However, former researches are inadequate for complex operations of weapon systems that are requirements of the engagement simulation. Thus, the construction of the engagement simulation system of which reflects environmental effects based on environmental data is still difficult. The main objective of this paper is to propose a framework to solve the difficulty and constructs an example system based on the proposed framework.

국방 시뮬레이션 유형은 워게임 모형으로 분류되는 Constructive 시뮬레이션, 실 기동에 의한 Live 시뮬레이션, 그리고 가상현실을 적용한 Virtual 시뮬레이션 등 3가지로 분류될 수 있다. 워게임 시뮬레이션은 일반적으로 대부대 훈련에 적합하지만 많은 가정사항을 내포하게 됨으로써 현실감이 떨어지고 실 기동 시뮬레이션은 실전적인 훈련이 가능하지만 전구급 수준의 대부대 훈련에의 적용이 곤란한 단점이 있다. 또한 이들 시뮬레이션 유형들은 개별적으로 운용됨으로써 각 유형들이 가지고 있는 취약점이 노출되고 있는 현실이다. STOW(합성전장 훈련체계, Synthetic Theater of War)는 실제훈련이 가능한 분야는 실 기동으로, 실 훈련이 불가능한 전장상황은 시뮬레이션 기법을 활용하여 상호결합 시킴으로써 각 시뮬레이션 유형들의 제한사항을 상호 보완하여 실제와 유사한 전장을 조성하여 훈련하는 종합적이고 체계적인 훈련체계로써 21세기에 예상되는 전쟁이외의 작전(OOTW), 비대칭전, 정밀타격 및 C4I를 모의할 수 있는 엔티티 수준의 합성전장이다. 본 고는 STOW의 구성요소(합성부대, 합성환경, 시뮬레이션 네트워크, 지형 DB 개발도구, C4I 인터페이스, 기반체계 등)를 국내기술 능력과 비교, 분석함으로써 우리의 여건에 적합한 STOW 체계 구축방안을 제시하고자 한다.

Presented in the paper is a methodology for the distributed simulation of underwater warfare based on standard synthetic environment. In the case of underwater warfare simulation, it is very important to reflect environmental data, such as salinity and temperature. For the reusability and interoperability of environmental data, this paper adopts Synthetic Environmental Data Representation and Interchange Specification (SEDRIS(ISO standard for environmental data)). Although SEDRIS provides various merits as an international standard, applying of SEDRIS has been hindered by its broadness and heaviness. To relieve the difficulties, this paper proposes an efficient procedure to utilize SEDRIS technology for the atmosphere and underwater environment. This paper identifies SEDRIS structure for the atmosphere/underwater structured dimensional grid-based and implements the proposed procedure on the High Level Architecture (HLA) / Run-Time Infrastructure (RTI) to explain the generation of the battlefield in a distributed simulation system.

Presented in this paper is a study for construction of a simulation system for the engagement of ground weapon systems. This paper proposes architecture for the simulation system based on agent simulation design methodology. Every entity of the proposed architecture is developed by assembling modularized agent components, and it enhances the reusability and composability of the entity. Consequently, time, costs, and efforts that are required to develop a new simulation system is able to be reduced by the enhancement. In the case of ground engagement simulation, it is very important to reflect environmental effects. Synthetic battlefield of the proposed architecture has environmental data of the battlefield and interacts with entities in the simulation system. The proposed architecture based simulation system can build swiftly various simulation models by the objectives and derive reasonable results from behaviors of entities that include environmental effects. This paper contains the construction of an example system based on the proposed architecture to verify the advantages of the architecture.

The US military is developing and improving SE-CORE and CVE to integrate war game between different kinds of systems, establish time-optimal CVE. Although South Korea is researching SEDRIS, etc. that is suitable for domestic circumstances, there are still many problems to be solved. The researchers suggest a way to semi-automate part of SNE process, by using the channel information of the image. This can help to improve speed of creating synthetic environment and facilitate information sharing to the others. If there is further research on the subject, it will be possible to develop automation technology to apply data from various information collection devices to synthetic battlefield environment (SBE).

LVC(Live-Virtual-Constructive) training system is drawing attention due to changes in battlefield situation and the development of advanced information and communication technologies. The ROKAF(Republic of Korea Air Force) plans to construct LVC training system capable of scientific training. This paper analyzes the results of V-C interoperability test with three fighter simulators as virtual systems and a theater-level wargame model as a constructive system. The F-15K, KF-16, and FA-50 fighter simulators, which have different interoperable methods, were converted into a standard for simulation interoperability. Using the integrated field environment simulator, the fighter simulators established a mutually interoperable environment. In addition, the Changgong model, which is the representative training model of the Air Force, was converted to the standard for simulation interoperability, and the integrated model was implemented with optimized interoperability performance. Throughput experiments, It was confirmed that the fighter simulators and the war game model of the ROKAF could be interoperable with each other. The results of this study are expected to be a good reference for the future study of the ROKAF LVC training system.
