The future warfare will universalize the operation of a combined weapon system that utilizes this technology and create an operational environment that is centered on a network requiring a high level of interoperability between combat elements as well as a high level of operation speed. In this kind of operational environment, future combat will take on the aspects of network centric warfare, which is capable of realizing a real-time sensor to shooter cycle by horizontally connecting operation elements. Therefore, the study attempts to draw out a Korean measurement plan concerning battlefield environment changes in the future by investigating and analyzing all problems occurring during the mass acquisition and processing of battlefield information in battlefield situations of network centric warfare currently conducted by the US military in Afghanistan and Iraq.

In this paper, we propose a method to analyze the clusters of RF threats emitting electrical signals based on collected signal variables in integrated electronic warfare environments. We first analyze the signal variables collected by an electronic warfare receiver, and construct a model based on variables showing the properties of threats. To visualize the distribution of RF threats and reversely identify them, we use k-means clustering algorithm and self-organizing map (SOM) algorithm, which are belonging to unsupervised learning techniques. Through the resulting model compiled by k-means clustering and SOM algorithms, the RF threats can be classified into one of the distribution of RF threats. In an experiment, we measure the accuracy of classification results using the algorithms, and verify the resulting model that could be used to visually recognize the distribution of RF threats.

Due to the rapid developments in information and computer technology, the warfare paradigm is being transformed into information-centric and knowledge-based warfare. This atmosphere may have significant impact on the ROK armed forces' Force Improvement Plans (FIP) which is documented in 'Defense White Paper 2004'. We focus here on the relationship of information-centric force and deterrence of invasion. Particularly, we are interested in understanding the level of information superiority that might be required to deter the invasion. In order to solve this problem, we employed two-sided, zero-sum strategic game to simulate the outcome with six hypothetical cases devised by varying the level of information superiority.

This study aims to analyze actual conditions of the present national defense information network operation, the structure and management of the system, communication lines, security equipments for the lines, the management of network and software, stored data and transferred data and even general vulnerable factors of our army tactical C4I system. Out of them, by carrying out an extensive analysis of the army tactical C4I system, likely to be the core of future information warfare, this study suggested plans adaptive to better information security, based on the vulnerable factors provided. Firstly, by suggesting various information security factor technologies, such as VPN (virtual private network), IPDS (intrusion prevention & detection system) and firewall system against virus and malicious software as well as security operation systems and validation programs, this study provided plans to improve the network, hardware (computer security), communication lines (communication security). Secondly, to prepare against hacking warfare which has been a social issue recently, this study suggested plans to establish countermeasures to increase the efficiency of the army tactical C4I system by investigating possible threats through an analysis of hacking techniques. Thirdly, to establish a more rational and efficient national defense information security system, this study provided a foundation by suggesting several priority factors, such as information security-related institutions and regulations and organization alignment and supplementation. On the basis of the results above, this study came to the following conclusion. To establish a successful information security system, it is essential to compose and operate an efficient 'Integrated Security System' that can detect and promptly cope with intrusion behaviors in real time through various different-type security systems and sustain the component information properly by analyzing intrusion-related information.

The paradigm of war is basically changed by development of information and communication technologies. One of the paradigms in future war is NCW(Network-Centric Warfare) that is purposed of achievement in information-superiority. In this future war, the level of menace and fragility is rapidly increased in information-security according to the massive information and complex system. Therefore the Korean army is developing the information-security technologies for NCW. But, until now patent analysis concerning NCW has not performed. In this paper, we suggest a meaningful data for efficient R&D through patent analysis of information-security technologies on NCW.

The 4th industrial revolution will develop the network environment of future warfare through the increase of IoT devices, individual warrior platforms, the operation of manned and unmanned weapon systems, intelligent command post. They are leading to the weapon system combined with hundreds or thousands of sensors will be used for surveillance and reconnaissance, electronic warfare, and deception operations on the battlefield. This change to the environment brings superiority in operational performance on the battlefield, but if the weapon system is exposed to the outside, it will lead to fatal results. In this paper, we analyze the network environment that is changing in the future warfare environment, focusing on the currently used network. In addition, it considers information security issues that must correspond to the evolving network technology and suggests various security measures to suggest the direction our military should take in the future.

Modern warfare is gradually changing into a network war, and information electronic warfare is also progressing. In modern war, electronic warfare is all military activity concerned with electromagnetic field use, such as signal collecting, communication monitoring, information analysis, and electronic attack. The one key function of signal collecting for enemy signal analysis, direction finding, collects the signal radiated from enemy area and then calculates the enemy direction. This paper examined the Watson-Watt algorithm for an amplitude direction finding system and CVDF algorithm for phase direction finding system and analyzed the difference in the direction finding accuracy between in the clean electromagnetic field environment and in the real operating field environment of electronic warfare system. In the real field, the direction finding accuracy was affected by the reflected field from the surrounding obstacles. Therefore, this paper proposesan enhanced direction finding process for reducing the effect. The result of direction finding by applying the proposed process was enhanced above $1.24^{\circ}$ compared to the result for the existing process.
