The modern warfare needs sharing tactical situation and Command and Control(C2) capacity. Lately, developing of C2 System for Soldiers has dramatically increased according to increase of asymmetric state of hostilities like a guerilla war or a street-to-street fighting. In this paper, we explain the concepts of C2 System for Soldiers and Smart Phone. We describe the proposed system composed of HMD equipment, Smart Phone, and exclusive software. This system provides that Soldiers have C2 capacity and share the image of a visual field. It also offers efficient military power disposition and understanding tactical situation in operations.

The Tactical Data Link System(TDLS) is a standardized communication link to exchange and interface positional, situational information, command and control in real time. It has been evalua ted that the link would play an important role for tactical interoperability, situation awareness, and execution of joint operations in the future war. But considering the rapidly changing war situations, even though being admitted the necessity of the TDLS of Army helicopter, one of superpowers in the Army, it is not yet built the detailed operational concept. Therefore, this work presents how to embody the TDLS through the systems engineering approach based on the TDLS operating concept analysis of helicopters-ground units.

As part of overseas defense program of the US's Trump administration, the military allies were asked to cover partial operation costs for the weaponry deployed at the US bases in their countries. This raised the Korean government's, as well as defense industry's interest in constructing a tactical/strategic communication network and investments are being made actively. Thus, in this study, the performances of WiMAX and WLAN have been compared and a tactical/strategic communication network has been constructed for simulation by using OPNET. As a result, the simulation for the network using combat tanks was successful. An average communication distance that can be achieved by WLAN in open terrain is about 200m as it has been designed on the premise of short-range wireless communications. When the distance was increased to 1km, the tanks could not receive data. By contrast, it was able to confirm that the WiMAX-based network has allowed smooth communications at the same distance. Based on this result, it can be concluded that using WiMAX for tactical operations will have much more merit than adopting WLAN as far as the distance is concerned.

A homing torpedo's performance can be expressed a function of many variables, i.e. technical and tactical variables. When designing a homing torpedo, these variables have to be decided upon. The system effectiveness of a homing torpedo can be determined by analyzing of these variables. This paper describes a procedure of simulation metamodelling using a Factor Analysis methodology. A simulation model was used in order to obtain the data base for analyzing detection probability of torpedo. By analyzing the main and interaction effects these variables on the analysis of detection probability, we will show the importance of certain variables, of a homing torpedo.

Most O4I Systems are considered as one of the major system in future Information Warfare. However, it is difficult to measure the effectiveness of force improvement when C4I System is used with other weapon systems, quantitatively. In this Paper, we propose a quantitative method to evaluate the force improvement effectiveness of KNTDS(Korea Naval Tactical Data System). This method utilized the Lanchester's equations and its applications. We also showed a numerical example based on a given scenario in a sea battle and the ASP(Analytic Hierarchy Process) Method is applied to verify its results.

ADAS is the air defense control system performing air surveillance and identification of ROK and near air. This system is self-developed by Air Force, currently operated successfully as the alternative system of MCRC. ADAS processes converting and combining transferred the real time radar data detected by radars. additionally, it displays significant radar data as producing in tracks. Then, it uses the message queue for IPC(Inter Process Communication). the various tactical data processed in the server is ultimately send to the network management process through the message queue for transmitting to the weapon director console. the weapon director receives this transmitted tactical data through the console to execute air defense operations. However, there is a problem that data packet is delayed or lost since the weapon Director does not receive as the amount of tactical data from the server overflowed with air tracks and missions increased. This paper improved the algorism to display and transmit the various tactical data processed from ADAS server to numbers of the weapon director console in the real time without any delay or lost. Improved the algorism, established at exercise, the development server in the real operation network and the weapon director console, is proved by comparing the number of sending tactical data packets in the server and receiving packets in the weapon director.

본 논문은 육군이 10년여의 연구개발을 통하여 2005년에 개발 완료한 지상전술 C4I체계(Army Tactical Command Information System, ATCIS)의 가치평가를 위한 분석의 틀과 그 실증분석 결과를 제시하고 있다. ATCIS의 가치평가를 위해 육군본부, 국방관련기관, 그리고 업체 등 관련기관들이 지원한 자료를 활용하고 해당분야 전문가들이 참여하였으며, 가능한 가치평가 방법론을 적용하여 합당한 가치평가의 들을 제시하고 이를 실증분석 하였다. 가치평가의 결과는 경제적, 기술적, 그리고 전략증장적 효과 측면에서 ATCIS에 대한 정성적, 정량적 가치로 제시하였으며 의국의 유사 시스템과 비교시 비용대효과 측면에서 최소 6.55배 이상이며, 약 1조 7,291억원 이상의 가치를 창출한 것으로 평가되었다. 본 연구의 의의는 무기체계 개발에 따라 요구되는 가치평가의 틀과 그 실종분석을 통해 향후 타 무기체계개발 가치평가 및 선행연구, 절충교역 기술가치평가 및 성과분석 등에 효과적으로 적용할 수 있는 구체적 방안을 제시하였다는데 있다.

Military training is an essential item for the fundamental problem of war. However, there has always been a problem that many resources are consumed, causing spatial and environmental pollution. The concepts of defense modeling and simulation and CGF(Computer Generated Force) using computer technology began to appear to improve this problem. The Naval Operations, Resources Analysis Model(NORAM) developed by the Republic of Korea Navy is also a DEVS(Discrete Event Simulation)-based naval virtual force analysis model. The current NORAM is a battle experiment conducted by an operator, and parameter values such as maneuver and armament operation for individual objects for each situation are evaluated. In spite of our research conducted evolutionary, supervised, reinforcement learning, in this paper, we introduce our design of a scenario creation model based on evolutionary learning using genetic algorithms. For verification, the NORAM is loaded with our model to analyze wartime engagements. Human-level tactical scenario creation capability is secured by automatically generating enemy tactical scenarios for human-designed Blue Army tactical scenarios.

본 논문에서는 NCW 환경에서 Link-16 전술데이터링크를 통해 이미지 정보를 신속 정확하게 전송하여 작전효율을 증대시키기 위한 메시지 패킹 기법을 제안한다. 제안하는 메시지 패킹구조는 기존의 Link-16 메시지와 호환성을 유지하면서 하나의 타임슬롯 내에서 데이터 전송율을 증가시킬 수 있도록 COC(Cyclic shifted Orthogonal Complementary) 웨이브폼의 가변 코드율을 적용하여 주파수 사용 효율을 향상시키고, 특히 동적 TDMA 환경에서 타임슬롯을 연속으로 전송 할 때, 시간 자원 이용률이 높은 패킹구조를 함께 사용하게 되면 동일한 타임슬롯내에 더 많은 데이터를 전송할 수 있도록 하였다. 모의실험을 통해 제안한 방식의 성능 및 우수성을 비교하고 제안 방식의 타당성을 보인다.
