This report shows the analysis and design of tactical decision automation procedure and the result of core algorithm. Expecially scheme of analysis and design includes result of tactical decision supporting procedure analysis for target engagement to fire in refer to AFATDS. Tactical decision automation procedure has three phases like target analysis, target priority, fire unit decision, fire method and attack method. Target analysis creates base information to decide priorities and attack methods through target activity, size and protection status. Target priority and fire unit decision judge target priority and fire unit with unit status and operation mission basis of target priority. Fire unit and Attack method decide fire style according to the kind of fire and ammunition for effective firing achievement. Finally, we show the effective tactical decision automation procedure through making the algorithm of priority and air control.

K9 BTCS의 성공적인 개발은 디지털화된 사격지휘 전산장비체계로 종심지원작전, 근접지원작전 그리고 대화력전을 수행하는 여건을 제공하였다. 또한 K9 자주포의 전술적운용 능력과 실시간 타격전력 발휘에 질적인 발전과 변화를 가져다 주었으며, 기존의 BTCS를 기반으로 하여 화력지원 사격지휘체계를 한 단계 높은 화력을 운용하도록 성능개량한 것으로, 무선에 의한 디지털 다중임무수행, 표적획득체계와의 연동운용, 상황도시 등을 윈도우 환경에서 운용할 수 있게 되었다. 이로써 $C^4I$체계상에서 SHOOT & SCOOT 전술적 운용과 효과중심의 탄약을 적시에 사용할 수 있게 하였고, 화력집중과 분산을 용이하게 하였다.

본 논문에서는 자동화 사격장 Pop-Up시스템의 안정성 및 성능 향상을 위해 예측제어기를 설계하여 시간지연에 따른 문제를 보상하였다. 확률 모델에 기반한 예측제어기는 지연된 이전의 값들로부터 선형예측 기법과 확률함수를 이용하여 실제의 값을 추정하며, 이를 제어기에 적용하여 시간지연에 따른 문제점을 최소화하였다. 제안된 알고리즘의 타당성을 검정하기 위해 사격용 Pop-Up시스템에 본 알고리즘을 실현하였으며, 상이한 시간지연과 이득 변화에 따른 제어기의 성능을 관측하였다. 실험결과 제안된 예측제어기는 시간지연에 대해 PID 제어기보다 빠른 수렴 특성을 보이며, 제어기의 안정범위 내에서 허용할 수 있는 최대 시간지연 값도 증가시킬 수 있었다. 따라서 사격용 타겟의 Pop & Up동작이 제어시간 이내에 원활하게 작동되어 연속 사격의 실시간 제어를 효율적으로 수행하였다.

This paper deals with an optimal Weapon-Target Assignment (WTA) algorithm for Closed-In Weapon Systems (CIWS), considering variable burst time. In this study, the WTA problem for CIWS is formulated based on Mixed Integer Linear Programming (MILP). Unlike the previous study assuming that the burst time is fixed regardless of the engagement range, the proposed method utilizes the variable burst time based on the kill probability according to the engagement range. Thus, the proposed method can reflect a more realistic engagement situation and reduce the reaction time of CIWS against targets, compared to the existing method. In this paper, we first reformulate the existing MILP-based WTA problem to accommodate the variable burst Time. The proposed method is then validated through numerical simulations with the help of a commercial optimization tool.

The Ministry of National Defense decided to build a realistic combat simulation training system based on virtual reality and augmented reality in accordance with the expansion of the scientific training system of "Defense Reform 2.0". The realistic combat simulation training system should be able to maximize the tension and training effect as in actual combat through engagement between trainers. In addition, it should be possible to increase the effectiveness of survival training at the same time as shooting training similar to actual combat through cover training. Previous studies are suitable techniques to improve the shooting precision of the trainee, but it is difficult to practice bilateral engagement like in actual combat, and it is particularly insufficient for combat shooting training using cover. Therefore, in this paper, we propose a S/W algorithm for generating a virtual avatar by recognizing the shooting posture of the opponent on the screen of the virtual shooting trainer. This S/W algorithm can recognize the trainer and the cover based on the depth information acquired through the depth sensor and estimate the trainer's posture.

This study suggests an indoor screen shooting system that can be connected with diverse graphic contents, through developing a gun only for indoor shooting and developing high-speed laser recognition algorithm. The dedicated gun has strong durability and was applied pneumatic solenoid valve control and invisible laser. The aim is to commercialize the indoor screen shooting system by developing a method of interacting with graphic engine through recognizing invisible laser at high speed.

무장 비행 궤적 간 간섭을 식별하여 아군 무장간 충돌을 방지함으로써 단위 시간 당 교전 효과를 극대화하는 것은 다무장 대지 무기체계 운용에 있어서 필수적이다. 기존 연구에서는 연산 부하의 최소화를 목표로 3차원 무장 비행 궤적을 2차원 평면의 사격선으로 변환하여 간섭을 식별하는 알고리즘을 제안하였다. 그러나 기존 연구는 2차원 평면에서 사격선간 교차점이 발생할 경우 간섭으로 식별하고, 이에 대한 무장 할당을 해제함으로써 무장 활용도를 감소시키는 문제가 있었다. 이를 고려하여 본 논문에서는 교전 효과 최대화를 위한 효율적인 무장 궤적 간 간섭 식별 알고리즘을 제안한다. 제안하는 알고리즘은 2차원 평면에서 사격선간 교차점이 발생할 경우, 해당 사격선을 3차원 평면에서 비행 궤적 간 비교 연산을 수행하여 실제 간섭 여부를 식별함으로써 무장 활용도를 최대화하는 것이 가능하다. 성능 평가 결과, 제안하는 기법은 기존 기법에 비해 궤적 교차수는 최대 52.1% 감소하였으며, 그에 따른 표적 할당율은 최대 6.9% 향상됨을 보임으로써 그 우수성을 확인하였다.

The rapid growth of virtual reality technology in the era of the 4th Industrial Revolution has accelerated scientification of combat training systems in addition to ICT(information and communications technology) in military field. Recently, research and development of simulators based on virtual reality have been actively conducted in order to solve sensitive issues such as increase of civil complaints due to the noise of a shooting range, prevention of shooting accident, and reduction of training cost. In this paper, we propose two key solutions: spatial synchronization method and modified point mass trajectory model with small angle approximation to overcome technical limitations of a current training simulator. A trainee who wears a haptic vest in a mixed reality environment built in MARS(medium-range assault rifle shooting simulator) is able to conduct not only precision shooting but also two-way engagement with virtual opponents. It is possible for trainee to receive more reliable evaluations in the MARS than an existing rifle simulator based on laser.

During artillery fire, an excessive level of impulse noise propagating in the form of a storm wave is generated. Since the sound of impact from the fire affects the stability of the surrounding structures, the artillery and the structures must be separated from each other by the proper distance to avoid damages from friendly fire. However, if they have already been built within the distance, it is possible to prevent the damages by building sound barriers between them. In this study, the proper separation distance between the artillery and the structure was calculated, and the insertion losses due to various heights and shapes of the sound barrier were simulated by using the BEM(Boundary Element Method), and conclusively the optimal sound barrier was selected.
