In order to estimate the life cycle expense of the weapon system acquisition from the first demand planning phase until the last disuse phase, we apply the reliable expense analysis method to the current situation in Korea by using the sensitivity analysis. We estimate the total cost of the weapon system acquisition by focusing on the most important variables such as exchange rate, and hence by strengthening the function of the existing expense analysis method, which is used to be simply recognized as a tool of cost reduction. Therefore, this study could make a contribution to the literature in this area, in terms of deriving the most cost-efficient method of acquisition by comparing the various estimated costs that result from the different alternatives of the weapon system acquisition.

In order for the military organization to be reborn as a high-tech science and technology strong force, science and technology that can be applied to the military is identified at the rapid development of science and technology, This should be quickly applied to military organizations, which is a growing consensus that Defense R&D planning system centered on rioters is needed to quickly acquire advanced weapons systems. In this respect, in order to successfully achieve the current government's defense policy, the high-tech weapons system necessary for national defense is required quicklyIt is necessary to closely examine defense planning, systems, organizations, and functions to develop into a high-tech science and technology military to link from raising to acquiring, and to reorganize the power enhancement and operation system. Therefore, this study proposes a high-efficiency defense operation system that combines advanced science and technology by Korean military organizations through "Defense Innovation 4.0", and we hope that follow-up research will be conducted following this study.

In recent years, the development of weapons systems in the field of defense research and development has become increasingly large, complex, and long-term, and so have budgets and the time spans involved. In order to improve this, the Weapon Systems Requirement Verification Committee, which benchmarked the preliminary feasibility of the private sector, was established to verify the appropriateness of requirements, and the necessity and priority of the projects. This research proposes a methodology for analyzing and prioritizing proposed weapons systems for effective and strategic allocation of defense budget funding. First, the evaluation factors that can be used in the defense sector were assessed by analyzing the related fields. We set the weighting of items by using the analytical hierarchy process for technical risk assessment and technical profitability evaluation. After that, we applied the methodology to 32 weapons systems and analyzed the results. In conclusion, through this study, it was possible to analyze profitability dimensions overlooked in the existing methodology.

A study on common modular design based on open standards to reduce the life cycle cost of ground weapon system is underway. Since the ground weapon system includes major mission equipment such as fire control system, it is essential to apply the concept of fault tolerance through automatic reconfiguration and blocking unspecified equipment through connectivity control. However, it is difficult to generalize due to the difference in operating characteristics for each system. In this paper, we propose a plug-and-play framework, which includes plug-and-play architecture and mechanism. The proposed method can be used in common by the application of each component as it is divided into a common service layer. In addition, the proposed connectivity control and autonomous reconfiguration method facilitates reflection of operating characteristics for each system. We constructed a verification environment that can simulate ground weapon systems and components, and verified that the proposed framework works through scenario-based functional tests.

1970년초 '자주국방'으로 시작한 방위산업의 역량은 재래식 무기의 국산화 단계를 넘어서 일부 첨단무기를 독자 개발할 수 있는 수준에 도달하였다. 하지만 그동안 방위산업 정책은 내수시장을 중심으로 이뤄졌었고, 방위산업체를 중심으로 한 제한된 경쟁체제였다. 그 결과 국방과학기술 경쟁력은 11위인 반면에 민수분야 과학기술경쟁력은 4위로 눈부신 발전을 하였다. 또한 2009년 스톡홀롬 국제평화연구소 발표에 따르면 우리나라는 무기 수입국 3위인 반면, 수출은 17위에 위치해 있다. 따라서 본 연구는 위와 같은 문제 인식을 바탕으로 시작하였으며, 특히 민수업체의 방산분야 참여를 통해 국내시장의 규모를 넓히고, 국내경쟁력 향상하고, 더 나아가 방위산업 글로벌 경쟁력을 확보하여 국가 방위력개선 뿐만 아니라 수출 선도 산업으로 자리매김할 수 있는 개방형 기술혁신체계 구축 방법을 모색하였다. 또한 민수분야의 조사를 통해 방위산업 진입장벽을 파악하였으며, 진입장벽 해소를 통해 방위산업 경쟁력 강화를 할 수 있는 방법을 고찰하였다. 국방분야의 개방형 기술혁신체계 구축은 국가과학기술을 선도하고, 군 전력증강 및 국가경제발전에 기여할 것이다.

The purpose of this study is to analyze the problems of current rules and regulations on the source selection for weapon system in defense acquisition project and suggest several techniques to ensure objectivity and fairness. As an application example, Helicopter source selection was presented. It was analyzed and compared through technique application and strength and weakness analysis of AHP, PROMETHEE and Attribute Transformation. The decision making techniques which make all conditions satisfactory in all situations are nonexistent. Thus, it is estimated that we can maintain the objectivity in the source selection of weapon systems by applying suitable decision making techniques in accordance with the patterns of evaluation item.

When tracking small UAVs and drone targets in cloud clutter environments, MWIR sensors are often unable to track targets continuously. To overcome this problem, the SWIR sensor is mounted on the same gimbal. Target tracking uses sensor information fusion or selectively applies information from each sensor. In this case, parallax correction using the target distance is often used. However, it is difficult to apply the existing method to small UAVs and drone targets because the laser rangefinder's beam divergence angle is small, making it difficult to measure the distance. We propose a tracking method which needs not parallax correction of sensors. In the method, images from MWIR and SWIR sensors are captured simultaneously and a tracking error for gimbal driving is chosen by effectiveness measure. In order to prove the method, tracking performance was demonstrated for UAVs and drone targets in the real sky background using MWIR and SWIR image sensors.

Technology planning in the defense field aims to develop core technologies in order to develop weapon systems to satisfy the force integration period by researching and analyzing necessary technologies for weapon systems. In the past, core technology development projects were conducted by deriving core technology based on the main required operational capability. But in this case, there is the limitation that technologies which are necessary to develop weapon systems but do not directly affect required operational capability, such as system integration technologies, are not considered. In this paper, we propose a work breakdown structure-based technology research and analysis methodology that prevents vacant technologies by identifying core technologies that must be secured for the development of weapon systems at the component level. With the proposed methodology, it is possible to identify technologies that must be acquired to realize the required operational capability of systems or which must be secured even they do not affect the required operational capability.

세계 여러나라의 유도무기체계에 적용되고 있거나 개발중인 착화기술의 개략적인 특성과 장단점을 제시하고 각 기술의 수행능력인 성능, 신뢰성, 안전성, 가격등을 비교분석하였습니다. 분석결과, 어느 무기체계에서나 만족될수 있는 만능적인 착화기술은 없으며 적응요구조건과 비용에 따라 각기 특별한 장단점을 가집니다. 그러나 현재 선진국에서 개발되어 시험 적용되고 있는 다이오드레이저를 이용한 착화방법은 본질적인 잇점들 때문에 차후 유도무기 착화기술에 지배적으로 사용될 것으로 판단됩니다
