This paper focuses on analyzing the modern warfare and weapon systems supported by improved GPS informations. The GPS capability was investigated through the real experimental test for verifying the most recent GPS features under its modernization processing. And then it was verified that such capabilities, accuracy and availability, of a typical L1, C/A code GPS receiver are equivalent to the military receiver's ones. It was also sure that the influence of GPS improved informations on NCW(Network-Centric Warfare), PGM(Precision Guided Munition) and C4SIR(Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance) should be increased and the modern warfare may be strongly dependent on GNSS informations.

본 연구는 현대 전쟁에서 드론 심리전의 사례를 분석하고, 그 효과와 한계를 살펴보는 것을 목적으로 한다. 미국, 이스라엘, 우크라이나의 사례를 중심으로 드론을 활용한 감시와 공격, 선전 활동이 적군의 사기와 전투 의지에 미치는 영향을 분석하였다. 연구 결과, 드론 심리전은 적군에게 심리적 압박을 가하고 전투 의지를 약화시키는 데 상당한 효과가 있는 것으로 나타났다. 그러나 민간인 피해와 국제법 위반 논란 등 심각한 부작용도 수반하고 있어, 이에 대한 윤리적 검토가 필요함을 지적하였다. 본 연구는 드론 심리전의 실효성과 윤리성에 대한 심도 있는 논의의 토대를 제공한다는 점에서 의의를 갖는다.

이 논문은 군사 드론의 기술적 발전과 그로 인한 현대 전쟁 및 국제 관계의 변화를 분석한다. 먼저, 군사 드론의 역사적 발전 과정을 살펴보고 현대 군사 드론의 주요 특징과 장단점을 분석하였다. 이어서 드론 기술이 전쟁 수행 방식과 군사 전략에 가져온 변화를 고찰하고, 드론 사용과 관련된 법적, 윤리적 쟁점을 논의하였다. 마지막으로 최근 전쟁 사례와 국가별 대응 사례를 통해 군사 드론의 실전 운용 현황과 그 영향력을 평가하였다. 본 연구는 우리군의 드론 운용 발전 방향과 국제사회가 직면한 드론 전쟁의 법적·윤리적 문제에 대한 해결 방안을 제안한다.

Modern warfare has developed into a network based simultaneous and integrated warfare where operations elements are interconnected. Following such change in modern warfare, ROK Army has been making an effort to transform personnel-based military structure into technology-based advanced structure. Considering technological innovations and changes in characteristics of officers and men, ROK Army is developing scientific education and training system to provide demand-focused customized education. To support such transformation in education and training, ROK Army is constantly developing Army training system using advanced M&S technology. This paper describes ROK Army's education and training policy, and elaborates the current status of M&S training system using advanced M&S technology. This paper further discusses the future directions of M&S training system.

The recent notion of Network Centric Warfare (NCW) emphasizes the ability to distribute the right information at the right time to maximize the combat effectiveness. Accordingly, in the modern combat system, the importance of non-physical elements, such as a communication system, is increasing. However, an NCW-support communication network system is expensive. Therefore, it is essential to develop a proper combat system evaluation method to establish an efficient NCW-support combat system. Traditionally, combat system effectiveness is measured in terms of physical elements such as men and fire power, Obviously, such method is hardly applicable to a modern combat system. To overcome this difficulty, we propose an evaluation model based on CA (Cellular Automata) simulation. A set of preliminary combat simulations show that CA simulation may be promising in evaluating non-physical element of a modern combat system.

Electronic warfare systems are needed to be advantageous in the modern war. Many radar threat signals with various frequency spectrums and complicated techniques exist. For detecting the threats, a receiver with wide and narrow-band digital processing is needed. To process a wide-band searching mode, a polyphase filter bank has become the architecture of choice to efficiently detect threats. A polyphase N-path filter aligns the re-sampled time series in each path, and a discrete Fourier transform aligns phase and separates the sub-channel baseband aliases. Multiple threats and CW are detected or rejected when the signals are received in different sub-channels. And also, to process a narrow-band precision mode, a direct down converter is needed to reduce aliasing by using a decimation filter. These digital logics are designed in a FPGA. This paper shows how to design and develop a wide and narrow-band digital receiver that is capable to detect the threats.

현대전에서는 전파를 이용하여 적의 정보를 알아내거나, 적이 탐지하려는 아군 정보를 보호하는 임무를 수행하는 전자전 분야의 중요성이 증가하고 있다. 전자전 분야의 대표적인 전자공격 방법 중 하나인 레이다 재밍기법은 적 레이다를 교란 및 기만하여 아군의 위치 정보가 노출되는 것을 방지한다. 레이다 재밍기법 중 하나인 속도기만 재밍기법은 도플러효과를 이용하여 표적의 속도와 위치를 추적하는 펄스 도플러 레이다를 대상으로 사용된다. 속도기만 재밍기법은 DRFM (Digital Radio Frequency Memory)을 이용하여 수신신호를 주파수 변조해서 송신하는 방법으로 구현할 수 있다. 본 논문은 위상 샘플방식 DRFM을 이용하여 속도기만 재밍기법 중 하나인 VGPO/VGPI 재밍기법을 구현하는 방안을 기술하고, 제작한 보드를 통해서 주입신호 환경 하에서 VGPO/VGPI 재밍기법의 동작을 검증하였다.

A look back at the history of war reveals that leaders/nations which were able to recognize beforehand the change in weaponary or the concept of implementing war achieved victory in war(battle) while those that were not able to do so lost. Along with the development of civilization, so too did the characteristics of war : from the first wave of war (ancient, Napoleon's war)$\rightarrow$ the second wave of war (The first and second World War) $\rightarrow$ to the third wave of war (The Gulf War, and the War in Iraq). Especially notable was the American led victory earned in the Afghanistan and Iraq wars which applied the Rapid Decisive Operations(RDO) concept according to the Effects Based Operations(EBO) following the Gulf War and 9.11. This is the time when methods of warfare is changing through development in military science technology and military innovation and when the change of the defense paradigm including those of the Korea - U.S. alliance is required. We should therefore prepare for the future by delving into the analysis of American Modern warfare and learn from it.

One of the hot issues on GNSS might be that China declared to broadcast the signal of the new Global Navigation Satellite System called Beidou-Compass in December 2011. The multi-GNSS systems with the existing GPS and GLONASS consist of more than 100 GNSS satellites and transmit their signals in near future. Many benefits are expected in accuracy, availability, integrity and increasing anti-jam performance. In this presentation, we have mainly investigated the latest issue for multi- GNSS and discussed spectrum analysis as well as the accuracy improvement issue. The use of the modern weapon system based on satellite navigation information was also briefly investigated in warfare.
