설계자에게는 타이타늄 합금과 PMCS 모두 경량화 수단을 제공하지만 타이타늄쪽의 가격이 더 효과적이며 획득 절차가 더 완전하게 개발되어 있다. 지난 수년동안 전투차량에서의 타이타늄 사용이 증가했으며 이와 같은 추세는 계속되리라는 전망이다. 모든 지상용 차량 특히 M1 에이브람스 주력전차의 중량을 경량화 시키려는 끊임 없는 긴박한 소요가 있어 왔다. 타이타늄 합금은 앞에서 언급한 것처럼 특성의 고유한 조합 때문에 생존성을 유지시키면서 충분한 경량화를 달성할 수 있는 가장 경쟁력 있는 비용을 제공한다

This paper presents an autonomous detection and aiming point computation of a battle tank by using RGB images. Maximally stable extremal regions algorithm was implemented to find features of the tank, which are matched with images extracted from streaming video to figure out the region of interest where the tank is present. The median filter was applied to remove noises in the region of interest and decrease camouflage effects of the tank. For the tank segmentation, k-mean clustering was used to autonomously distinguish the tank from its background. Also, both erosion and dilation algorithms of morphology techniques were applied to extract the tank shape without noises and generate the binary image with 1 for the tank and 0 for the background. After that, Sobel's edge detection was used to measure the outline of the tank by which the aiming point at the center of the tank was calculated. For performance measurement, accuracy, precision, recall, and F-measure were analyzed by confusion matrix, resulting in 91.6%, 90.4%, 85.8%, and 88.1%, respectively.

The use of robot is no longer limited in the industrial scene, and becoming expanded toward many aspects of human life. Especially, military robot closely concerned with our lives seems to advance more and more in the future. As a need analysis for developing military robot, this project conducted a poll about Unmanned Reconnaissance Robot, and on the basis of the result, I suggested 3 directions of developing UGV(Unmanned Ground Vehicle) suitable to strategic environment of Korea.

The keen global competition is expected among foreign advanced nations for source, key technologies required by unmanned combat ground vehicle. Therefore, the trend of technologies for unmanned ground combat vehicle was analyzed in this research. It was based on the submitted patents from 1988 to 2008 in Korea, U.S.A, Japan, Europe, Canada and Israel. This analysis was focused on finding the technical level, the challenge area and breakthrough technologies and the growth of technologies of each nations considering opinions of experts. This report suggested the field of key technology development

Under combat simulation environment when inputting the detection performance data of the real system into the simulated object the given data affects the simulation analysis result. ACQUIRE-Target Task Performance Metric (TTPM)-Target Angular Size (TAS) model is used as a target acquisition model to simulate the detection ability of entities in the main combat simulation tool. This model estimates the decomposition curve of the object sensor and output the detection distance according to the target type. However, it is not easy to apply the performance of the new detection object that the user wants to input to the target acquisition model. Users want to input the detection distance into the target acquisition model, but the target acquisition model requires sensor decomposition curve data according to encounter conditions. In this paper, we propose a method of inversely deriving the sensor decomposition curve data of the target acquisition model by taking the detection distance to the target as an input. Here, the sensor decomposition curve data simultaneously satisfies each detection distance for three types of targets: personnel, ground vehicles, and aircraft. Finally, the detection distance of various reconnaissance equipment is applied to the detection object, and the detection effect according to the reconnaissance equipment is analyzed.

Today's unmanned technology, which is being used in various industries, is expected to be able to make autonomous judgements as autonomous technology matures, in the long run aspects. In order to improve the usability of unmanned system in the military field, it is necessary to develop a technique for systematically and quantitatively analyzing the efficiency and effectiveness of the unmanned system by means of a substitute for the tasks performed by humans. In this paper, we propose the method of representing rule-based tactical behavior and modeling manned and unmanned reconnaissance agents that can effectively analyze the path alternatives which is required for the future armored cavalry to establish a reconnaissance mission plan. First, we model the unmanned ground vehicle, small tactical vehicle, and combatant as an agent concept. Next, we implement the proposed agent behavior rules, e.g., maneuver, detection, route determination, and combatant's dismount point selection, by NetLogo. Considering the conditions of maneuver, enemy threat elements, reconnaissance assets, appropriate routes are automatically selected on the operation area. It is expected that it will be useful in analyzing unmanned ground system effects by calculating reconnaissance conducted area, time, and combat contribution ratio on the route.

The Battlefield Management System(BMS) of Ground Fighting Vehicles has employed its own message format but there have been requirements of using the standard message format, KVMF. To meet these requirements, we analyzed BMS and KVMF and incorporated KVMF into BMS. In this paper, we would like to introduce our implementation of KVMF in BMS.

In Korea, the birth rate is rapidly decreasing in the 21st century. Accordingly, if the current military service and personnel system are maintained, it will be difficult to maintain even the number of the Army reduced to 365,000. Nevertheless, the Army has a mission to protect the country from external aggression as the last bastion of national defense. To fulfill this mission, there are ways to improve the military service and personnel system, but there are ways to maximize individual combat power to create one warrior that is worth a hundred and overcome the insufficient number of troops through superior mobility to the enemy. This study studied how to solve the shortage of troops as well as strengthen combat power through a combined combat system that can maximize individual combat power and mobility by applying the latter concept, and further analyzed the future battle environment and suggested the developmental direction of the army's combined combat system.

Vulnerability assessment is a process to calculate the damage degree of a combat vehicle when the combat vehicle is attacked by an enemy. When the vehicle is hit, it is necessary to analyze the shot line to calculate which components are damaged and judge whether the armor of the vehicle is penetrated by enemy's warhead. To analyze the shot line efficiently, this paper presents the target modeling and the shot line analysis system to assess vulnerability of the ground combat vehicle. This system is easily able to do several functions: 1) the program reads STL files converted from CAD model which is designed by commercial CAD software. 2) It calculates the intersection between triangle of STL mesh and the shot line, and check if the components of the model are penetrated. 3) This program can visualize the results using OpenGL. The vulnerability assessment using the shot line analysis can be used to model the armor of the combat vehicle and arrange the inner components effectively in the early stage of development of the combat vehicle.

Enemy information has significant value when it comes to the process of military actions in battle field. Our Army now uses Battlefield Management Systems(BMSs) equipped in Ground Fighting Vehicles(GFVs) and we need to make research on what kind of role enemy information can play in such systems. Also, enemy information can be shared among GFVs and target information shall be extracted from it in view of KVMF scheme. Because KVMF becomes requisite standard in modern BMSs, we need to implement target information handling process in KVMF standard. In this article, we will focus on how target information and its sharing process can be managed efficiently without information conflicts. Also, situation map produced by it will be noted.
