무기체계 소프트웨어 개발 시 수행하는 신뢰성 시험은 크게 정적 검증과 동적 검증으로 구분된다. 정적 검증에서는 소프트웨어 코드를 수행시키지 않고 코딩 규칙 점검, 취약점 점검, 소스 코드 메트릭 점검을 수행하고, 동적 검증에서는 요구 사항을 기반으로 실제 소프트웨어를 실행시켜 기능을 검증하고 코드 실행률을 측정한다. 이러한 정적/동적 검증의 목적은 소프트웨어에 존재하는 결함을 발견하기 위한 것이다. 그러나 현재의 무기체계 소프트웨어 신뢰성 시험만으로는 여전히 탐지할 수 없는 결함들이 존재한다. 본 논문에서는 소프트웨어에서 발생할 수 있는 결함에 대해 무기체계 신뢰성 시험의 정적 검증과 동적 검증으로 탐지를 할 수 있는지를 사례실험을 통하여 분석 한다. 그 결과로 현재의 정적 검증과 동적 코드 커버리지 측정에서 더 나아가 무기체계 신뢰성 시험, 특히 동적 시험의 개선방안으로 연결하고자 한다.

A Technical Manual is the tool that offers a guidance to a maintenance engineer in order to exactly use and maintain of complicated weapon system. Because the modern weapon system are complex and functionality integrated, its quantity is massive. So We spend a lot of money on its publication and suspending recent information. To solve this problem, to reduce a risk of loss and use easily, this study develops the IETM(Interactive Electronic technical manual) which observes the CALS standard. This paper provide the development concept, environment, technic of IETM.

The development of a guided weapon system, such as a tactical missile, requires a performance analysis of a nonlinear system. Generally, the Monte Carlo analysis method is used for this purpose. The limitation of this method, a large number of simulations, for a nonlinear system performance analysis strongly motivated the development of a more efficient analytic technique. In this paper, the statisfical linearization methods is used for the performance analysis to the guided weapon system with the help of covariance analysis technique. Because the statistical linearization methods cannot be used to the look-up table nonlinear form such as aerodynamic coefficients, the second order polynomial representations is obtained from the table using the Lagrange interpolating polynomial and linearized statistically. Simple simulations about initial state conditions and random component in guidance command shows the results of this technique.

An effective method for produce munitions effectiveness data is to calculate weapon effectiveness indices in the US military's Joint Munitions Effectiveness Manuals (JMEM) and take advantage of the damage evaluation model (GFSM) and weapon Effectiveness Evaluation Model (Matrix Evaluator). However, a study about the Range Safety that can be applied in the live firing exercises is very insufficient in the case of ROK military. The Range Safety program is an element of the US Army Safety Program, and is the program responsible for developing policies and guidance to ensure the safe operation of live-fire ranges. The methodology of Weapon Danger Zone (WDZ) program is based on a combination of weapon modeling/simulation data and actual impact data. Also, each WDZ incorporates a probability distribution function which provides the information necessary to perform a quantitative risk assessment to evaluate the relative risk of an identified profile. A study of method to establish for K-Range Safety data is to develop manuals (pamphlet) will be a standard to ensure the effective and safe fire training at the ROK military education and training and environmental conditions. For example, WDZs are generated with the WDZ tool as part of the RMTK (Range Managers Tool Kit) package. The WDZ tool is a Geographic Information System-based application that is available to operational planners and range safety manager of Army and Marine Corps in both desktop and web-based versions. K-Range Safety Program based on US data is reflected in the Korean terrain by operating environments and training doctrine etc, and the range safety data are made. Thus, verification process on modified variables data is required. K-Range Safety rather than being produced by a single program, is an package safety activities and measures through weapon danger zone tool, SRP (The Sustainable Range Program), manuals, doctrine, terrain, climate, military defence M&S, weapon system development/operational test evaluation and analysis to continuously improving range safety zone. Distribution of this K-range safety pamphlet is available to Army users in electronic media only and is intended for the standing army and army reserve. Also publication and distribution to authorized users for marine corps commands are indicated in the table of allowances for publications. Therefore, this study proposes an efficient K-Range Safety Manual producing to calculate the danger zones that can be applied to the ROK military's live fire training by introducing of US Army weapons danger zone program and Range Safety Manual

최근 GPS 시스템이 적과의 교전에서 우수한 정밀도를 달성할 수 있기 때문에 GPS 유도무기들이 육상, 해상 및 공중의 많은 분야에 적용되고 있다. 특히, GPS 유도무기가 발사 되었을 때 현재의 위치를 확인하고 정확한 목표물의 방향을 찾아간다. 그러나 GPS 신호의 미약함으로 인한 취약성이 노출되어 있어 재밍신호가 특정 방향에서 강하게 유입될 경우 GPS 유도무기가 재밍될 수 있다. 따라서 이러한 상황 하에서 재밍대응 기술이 매우 중요하게 대두되고 있다. 본 논문에서는 GPS 유도무기의 재밍대응을 위해 방위각 제어를 이용하였다. 먼저, SLAM-ER, JDAM과 같은 GPS 유도방식의 정밀유도무기에 대하여 조사하였으며, 유도무기가 발사 후 항법도중 재밍이 되지 않도록 제어 가능한 방위각을 실험을 통해 분석하였다. 분석결과 140도 이하의 방위각 제어까지 안정적으로 GPS 유도무기가 정상 작동할 수 있음을 확인하였다.

Quantum-inspired Genetic Algorithm (QGA) is a probabilistic search optimization method combined quantum computation and genetic algorithm. In QGA, the chromosomes are encoded by qubits and are updated by quantum rotation gates, which can achieve a genetic search. Asset-based weapon target assignment (WTA) problem can be described as an optimization problem in which the defenders assign the weapons to hostile targets in order to maximize the value of a group of surviving assets threatened by the targets. It has already been proven that the WTA problem is NP-complete. In this study, we propose a QGA and a hybrid-QGA to solve an asset-based WTA problem. In the proposed QGA, a set of probabilistic superposition of qubits are coded and collapsed into a target number. Q-gate updating strategy is also used for search guidance. The hybrid-QGA is generated by incorporating both the random search capability of QGA and the evolution capability of genetic algorithm (GA). To observe the performance of each algorithm, we construct three synthetic WTA problems and check how each algorithm works on them. Simulation results show that all of the algorithm have good quality of solutions. Since the difference among mean resulting value is within 2%, we run the nonparametric pairwise Wilcoxon rank sum test for testing the equality of the means among the results. The Wilcoxon test reveals that GA has better quality than the others. In contrast, the simulation results indicate that hybrid-QGA and QGA is much faster than GA for the production of the same number of generations.

This paper analyzes the state of the art on the non-lethal disabling technologies(NDTs) and provides the direction for the development and use of non-lethal weapons. A dozen categories of NDTs are surveyed and explored for the prospective military operations in the future. These technologies may be mixed and matched for a specific purpose that would be potent yet safer than conventional lethal weapons. Many commonly available technologies that are either directly applicable as NDTs or with some engineering adaptation should be first considered to develope. These are NDTs for anti-mobility as follows: anti-traction technology, polymer agents and combustion alternation technology. Non-lethal weapons especially useful in our situation include destroying weapon-guidance systems, disabling engines of aircrafts and ground vehicles and C4I systems.
