ACTD(Advanced Concept Technology Demonstrations) exploit mature technologies to solve important military problems. A declining budget, significant changes in threats, and an accelerated pace of technology development have challenged our ability to adequately respond to rapidly evolving military needs. This work descibes ACTD processes, management, and ACTD programs case. It is presesyed a defense acquisition program applied ACTD.A scheme of the defense asquisition program using ACTD met military needs and technology readiness level is described.

SUGVs (Small Unmanned Ground Vehicles) are being used to conduct dangerous missions, such as EOD (explosive ordinance disposal), counter-terrorism operations, fire extinguishing and fire-fighting reconnaissance, reconnaissance of disaster areas, and surveillance of contact areas. Technology leading countries, the United States, United Kingdom, France, Germany, and Israel, have developed and operated various SUGVs for use in the military and civilian fields. The developed system was upgraded further based on additional requirements associated with data collected during the actual operation. The development trends of technology leading countries are an important indicator for the future development of SUGVs. In this study, the development trends and missions of SUGVs operating in the technology leading countries were analyzed. Based on the development trends of SUGVs in these countries, this paper discusses the features and design characteristics needed for the development of SUGVs in future military and civilian domains.

In this paper we suggested a performance evaluation model for future weapon systems. Weapon Performance Index(WPI) model transform the characteristics of alternatives as indices. We can easily obtain WPIs of alternatives with the model. The highest WPI recommended as the best solution. The performance elements in hierachy for future weapon systems are determined by systems engineering procedure. Priorities in hierachy can be determined through survey of experts engineering procedure. Priorities in hierachy can be determined through survey of experts and statistical analysis. Utility function is formulated as a probability model and utility score is predicted on the basis of historical data about the same category of weapon systems in the world. WPI is calculate from sum of product of priorities and utility scores. The model can be applied to trade-off analysis, cost and effectiveness analysis, war game model.

This paper deals with the consensus problem for multi-agent linear dynamic systems with directed communication topology. All the agents are identical high-order linear systems and their state information is exchanged through a communication network with directed graph. It is shown that a consensus is achieved if there exists a feasible solution to a set of linear matrix inequalities obtained for a simultaneous stabilization problem for multiple systems. Examples are presented to show the effectiveness of the proposed method.

A systems engineering is an interdisciplinary engineering management process that evolves and verifies an integrated, life-cycle balanced set of system solutions that satisfy customer needs. This work describes analysis of. the defense R & D programs applied systems engineering approach. FA-18E/F and NSSN defense acquisition programs are adopted for the case study. Those two programs is performed by IPPD, which is one of the systems engineering management techniques. From the analysis results, implementation considerations of domestic defense R & D programs are presented.

The operational concept of control systems on surface combatants has been changed from individual control for each system to integrated control for all systems due to computing technology development and crew reduction policy of navy. The purpose of this study is to identify current status of control technology, to analyze user requirement and to develop an architecture to support the conceptual change of ship control. An architecture, which integrates several control and monitoring systems on naval surface combatant, is proposed. The proposed architecture is focused on sharing network and computing resources related to user command, and reducing systems complexity. The architecture can be adopted to next surface combatants in Korean navy.

Unmanned Aerial Vehicles (UAVs) have been considered as valuable aerial reconnaissance systems and our army wants capability-enhanced UAVs installed in our territory, hoping that the UAVs will provide enemy information in detail. The enemy information acqcuired by UAVs would be shared by our army's legacy systems. In this article, we made a research on the interoperability between UAVs and Ground Fighting Vehicles (GFVs), laying emphasis on what kinds of tactical information could be exchanged by two different weapon systems. Also, it needs to be addressed that their upper-level commanding systems play a significant role in such operation.

The fire effectiveness and the operationability of the ground weapon system (such as tank, armored vehicle, howitzer, MLRS, ${\cdots}$), whose operations are usually happened on the ground, are dependent not only on their performances but also on the terrain environments. Especially, the artillery weapons systems' effectiveness is largely varied, because their maneuverability (such as translation, occupation of their sites) and the fire effectiveness are very dependent on the terrain. In this paper, presented are the methods how to analyze the terrain using the digital terrain data. And a software (which are implemented on the IBM PC compatible personal computer) is developed for the analysis of the terrain using the various method of computer Aided Geometric Design and Modeling. The S/W is expected to be very useful for the evaluation of the artillery weapon systems and for the commanders' decision making.

Reliability analysis and prediction of next failure time is critical to sustain weapon systems, concerning scheduled maintenance, spare parts replacement and maintenance interventions, etc. Since 1981, many methodology derived from various probabilistic and statistical theories has been suggested to do that activity. Nowadays, many A.I. tools have been used to support these predictions. Support Vector Regression(SVR) is a nonlinear regression technique extended from support vector machine. SVR can fit data flexibly and it has a wide variety of applications. This paper utilizes SVM and SVR with combining time series to predict the next failure time based on historical failure data. A numerical case using failure data from the military equipment is presented to demonstrate the performance of the proposed approach. Finally, the proposed approach is proved meaningful to predict next failure point and to estimate instantaneous failure rate and MTBF.

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.
