양인아,최우균,정경욱,심동혁,손동협 한국군사과학기술학회 2022 한국군사과학기술학회지 Vol.25 No.1

"Electronic equipment mounted on military vehicles is exposed to external shocks and vibrations. This causes problems in tactical operation and also causes cost loss in equipment maintenance. Therefore, to optimize the test standards for military vehicles with vibration, dynamic characteristics should be analyzed and standardized through actual driving tests. In this paper, the internal structure of 2.5tons military vehicle is designed in the form of a drawer and lathe, and the dynamic characteristics are identified by experiment, and the design is proposed."

This work describes a derivation process of JIC(Joint Integrating Concept) based JFC(Joint Functional Concept) analysis of an Aegis BMD(Ballistic Missile Defense). JIC is developed through JOC(Joint Operating Concept) and JFC based on capstone strategy and concept. Aegis BMD is a sea-based ballistic missile defense to detect ballistic missile threat, increase engagement battlespace and enable multiple engagement based on Aegis ships. Aegis BMD is a good case of JIC due to performing an Joint operations based on System of Systems under highly complicated NCW environment. This work analyses JFC using QFD(Quality Function Deployment) and UJTL(Universal Joint Task List). From this analysis the JIC of Aegis Korean BMD is derived using a CASE tool.

권용수,박은주,Kwon, Yong-Soo,Park, Eun-Joo 한국군사과학기술학회 2009 한국군사과학기술학회지 Vol.12 No.1

This work describes the possibility of ABL(Airborne Laser) applications to the Korean missile defense. The missile defense system is the multilayered defense system that consists of shooters, sensors and BM/C4I. The ABL is the missile defense system of boost phase. It is placing a high energy, megawatt class chemical oxygen iodine laser and highly sophisticated beam control/fire control and battle management systems on a modified Boeing 747-400F aircraft to detect, track and destroy ballistic missiles in their boost phase of flight. This work analysis the ballistic missile's threat of North Korea and the flight trajectory for the SCUD missile that is cut-off by the ABL. From this analysis the possibility of the ABL applications to the Korean missile defense is presented.

The low-altitude PAC-2 Patriot missile system is the backbone of ROK air defense for intercepting enemy aircraft. Currently there is no missile interceptor which can defend against the relatively high velocity ballistic missile from North Korea which may carry nuclear, biological or chemical warheads. For ballistic missile defense, Korea's air defense systems are being evaluated. In attempting to intercept ballistic missiles at high altitude the most effective means is through a multi-layered missile defense system. The missile defense problem has been studied considering a single interception system or any additional capability. In this study, we seek to establish a mathematical model that's available for multi-layered missile defense and minimize total interception fail probability and proposes a solution based on genetic algorithms. We perform computational tests to evaluate the relative speed and solution of our GA algorithm in comparison with the commercial optimization tool GAMS.

Next Generation Weapon system from the center of the platform to share information in real-time Network Centric Warfare(NCW: Network Centric Warfare) has been changed. Data link system is defined as a network. That is, all in real-time battlefield information is to enable sharing. Data link system is classified as a precision strike, Monitoring/control, control of a Patriot missile battery systems. These systems are most effective in a Joint warfare and precision strike. Data Link Systems(Data Communications) implementation is accomplished by using the KDLM(Korean Data Link Modem) and Radio Transceiver. KDLM is operated in conjunction with the legacy Radios(re-using fielded HF/VHF/UHF radio systems). In this paper, we describe in terms of KDLM system design. In this paper, the proposed design structure is how to effectively interact with legacy various radio. First, The results provide an analysis of that Dynamic TDMA system and apply modem structure. Radio characteristics data are necessary for an effective TDMA system design. This article analyzes the test results and describes the structure to improve the receive performance.

Recently, in the defense sector, there has been much interest in acquiring weapon systems that incorporate new technologies of the 4th industrial revolution, such as artificially intelligence. This study is about the technological convergence and diffusion of patents related to AI and military technology. We extracted domestic defense AI patents including both military and AI technologies applied from 2015 to 2023, then their cited patents extracted. The analysis shows that the Defense research institute and some defense industry companies are playing a key role, but Defense AI patent applications in the civilian fields was more than that in the military fields. In addition, the convergence of AI and military technology was expanding both scope and field. The significance of this study is that it confirmed the convergence and diffusion of defense AI technology and temporal changes, and also suggested the direction of defense R&D for the spin-on of new civilian technologies.

Demilitarization involves the disposal and recovery of obsolete explosives or ammunition. Cyclotol has been used as a military explosive along with RDX and HMX. A limited number of processes exist for safe disposal due to their sensitivity to thermal shock. Rotary kilns are widely used for thermal decomposition in many countries due to cost effectiveness and simplicity compared with supercritical oxidation. Phase change as well as condensed phase reactions(CPRs) and gas phase reactions(GPRs) with rates described by the Arrhenius equation of cyclotol has been considered in this work. Changes in gas fraction, reaction rate and mass of explosives were predicted at 490, 505 and 575 K. A maximum temperature of 2062 K has been predicted within the reactor at an initial temperature of 575 K due to GPRs. From this research, Thermal decomposition in the rotary kiln is plausible for demilitarization.

Technology growth curve methodology is commonly used in technology forecasting. A technology growth curve represents the paths of product performance in relation to time or investment in R&D. It is a useful tool to compare the technological performances between Korea and advanced nations and to describe the inflection points, the limit of improvement of a technology and their technology innovation strategies, etc. However, the curve fitting to a set of survey data often leads to model mis-specification, biased parameter estimation and incorrect result since data through survey with experts frequently contain outlier in process of curve fitting due to the subjective response characteristics. This paper propose a method to eliminate of outlier from a technology growth curve using M-estimator. The experimental results prove the overall improvement in technology growth curves by several pilot tests using real-data in Defense Science and Technology Survey reports.

조신영,곽용길,오현석,주혜선,박홍우 한국군사과학기술학회 2024 한국군사과학기술학회지 Vol.27 No.3

This paper describes a progressive test and evaluation strategy for verification of Korean Fighter eXperimental(KF-X) AESA(Active Electronically Scanned Array) radar development. Three progressive stages of developmenttest and evaluation were officially performed from simulated test conditions to actual operating conditions accordingto standards: radar function/performance and avionics integration. KF-X AESA radar development is repeatedlyverified by progressive stages consisting of five tests: Roof-lab ground test, System Integration Laboratory(SIL)ground test, Flying Test Bed(FTB) test, KF-X ground test, and KF-X flight test. As a result, the risk factordecreases as stages and tests progress. Therefore, development test and evaluation of KF-X AESA radar aresuccessfully performed at low development risk.
