제2차 세계대전 중에 최초의 탄도미사일인 V-2가 등장한 이후 발전하는 과학기술에 힘입어 미사일의 사거리, 정밀도 등이 비약적으로 향상됨에 따라 탄도미사일의 위협은 나날이 커지고 있다. 미국은 탄도미사일의 위협으로부터 자국 및 동맹국을 보호하기 위해 탄도미사일 방어체계(BMDS, Ballistic Missile Defense System)를 운용하고 있다. 센서에 의해 탐지된 탄도미사일은 요격 체계의 종류에 따라 부스트단계(Boost phase), 중간단계(Midcourse phase), 종말단계(Terminal phase) 등에서 요격하게 되며, THAAD(Terminal High Altitude Area Defense)는 고고도 종말단계에서 요격하는 체계이다. 본 논문에서는 미국의 탄도미사일 방어체계의 개념에 대해 간략히 설명하고, 그 중 THAAD의 운용 및 기술적 특징에 대해 집중적으로 조사하여 정리하였다.

미국은 러시아, 중국, 북한 등 주변국으로부터 탄도미사일의 위협이 증가함에 따라 미사일 방어체계를 구축하고 있다. 미국의 탄도미사일 방어체계는 미사일방어국(MDA, Missile Defense Agency)을 중심으로 통합 대공 및 미사일 방어(IAMD, Integrated Air and Missile Defense) 개념으로 이루어지며, 해군은 탄도미사일을 해상에서 탐지, 추적 및 요격하는 임무를 담당하고 있다. 본 논문에서는 미 해군의 이지스 탄도미사일 방어(Aegis Ballistic Missile Defense)의 개념과 구축 현황 및 계획을 조사하여 기술하였다.

미국은 직접적 잠재적 위협국에서 발사하는 탄도미사일 공격으로부터 본토를 방어하기 위해 탄도미사일 방어체계를 구축하여 운용하고 있다. 미사일 방어국(Missile Defense Agency)은 해상에서는 탄도미사일 방어체계가 탑재된 이지스함(Aegis BMD), Sea-Based X-band 레이더(SBX) 등을, 육상에서는 Ground-Based Interceptor(GBI), Early Warning 레이더, THAAD 등을 운용하고 있으며, 이에 추가하여 하와이에 탄도미사일 방어용 레이더(HDR-H)를 설치 할 예정이다. HDR-H가 전력화되면 아시아-태평양 지역에서의 탄도미사일 도발에 대한 대응 능력이 향상될 것으로 기대된다.

With the development of modern science and technology, weapon systems such as tanks, submarines, combat planes, radar are also dramatically advanced. Among these weapon systems, the ballistic missile, one of the asymmetric forces, could be considered as a very economical means to attack the core facilities of the other country in order to achieve the strategic goals of the country during the war. Because of the current ballistic missile threat from the North Korea, establishing a missile defense (MD) system becomes one of the major national defense issues. This study focused on the optimization of air defense artillery units' deployment for effective ballistic missile defense. To optimize the deployment of the units, firstly this study examined the possibility of defense, according to the presence of orbital coordinates of ballistic missiles in the limited defense range of air defense artillery units. This constraint on the defense range is originated from the characteristics of anti-ballistic missiles (ABMs) such as PATRIOT. Secondly, this study proposed the optimized mathematical model considering the total covering problem of binary integer programming, as an optimal deployment of air defense artillery units for defending every core defense facility with the least number of such units. Finally, numerical experiments were conducted to show how the suggested approach works. Assuming the current state of the Korean peninsula, the study arbitrarily set ballistic missile bases of the North Korea and core defense facilities of the South Korea. Under these conditions, numerical experiments were executed by utilizing MATLAB R2010a of the MathWorks, Inc.

The low-altitude PAC-2 Patriot missile system is the backbone of ROK air defense for intercepting enemy aircraft. Currently there is no missile interceptor which can defend against the relatively high velocity ballistic missile from North Korea which may carry nuclear, biological or chemical warheads. For ballistic missile defense, Korea's air defense systems are being evaluated. In attempting to intercept ballistic missiles at high altitude the most effective means is through a multi-layered missile defense system. The missile defense problem has been studied considering a single interception system or any additional capability. In this study, we seek to establish a mathematical model that's available for multi-layered missile defense and minimize total interception fail probability and proposes a solution based on genetic algorithms. We perform computational tests to evaluate the relative speed and solution of our GA algorithm in comparison with the commercial optimization tool GAMS.

This paper provides an empirical assessment of the development of North Korea's Anti-Ship Ballistic Missile (ASBM), and its influence on South Korea's maritime strategy. While research studies on North Korea's ballistic-missile capabilities and South Korea's ballistic-missile defense systems are proliferating, less analytical attention has been given to the way that the strengthening of North Korea's ballistic-missile capacities presents a critical threat to the ROK's navy and lines of communication. The authors of this paper identify the continuing development of unique ASBM capabilities by China and Iran, and determine that such processes are mutually interactive and in accordance with threat perceptions; furthermore, North Korea can enact the same process by learning lessons from these nations. The findings of this paper provide an implication for the formulation of South Korea's maritime strategy and the related assets in consideration of the ASBM as a future threat.

This paper describes the operational concept of the Aegis ship's missile defense. Recently, North Korea conducted a fourth nuclear-weapon test that involved the launch of a long-range missile and the underwater launch of an SLBM. The ground-based BMD (Ballistic Missile Defense) system is very limited for the SLBM of a miniaturized nuclear warhead; therefore, it is necessary to build a reliable sea-based missile-defense system. The ROK Navy has, however, only utilized the Aegis ship that is designed with a search-and-tracking sensor but is without a ballistic-missile interception capability. Given this information, this work focuses on the operational concept of the Aegis BMD by comparing the BMD capabilities of the ROK with those of the U.S.

In most cases, the trajectory of a ballistic missile is well explained by the Kepler's laws. It implies that the remaining trajectory of the ballistic missile including its final destination can be easily predicted if the position and velocity vector of the ballistic missile at any point on its path can be exactly known. Hence, an effective tracking algorithm based on an exact radar measurement model is very important for developing Ballistic Missile Defense(BMD) system. In this paper, we address to design a nonlinear filter, Unscented Kalman Filter(UKF), to track the ballistic missile.

This work describes the possibility of ABL(Airborne Laser) applications to the Korean missile defense. The missile defense system is the multilayered defense system that consists of shooters, sensors and BM/C4I. The ABL is the missile defense system of boost phase. It is placing a high energy, megawatt class chemical oxygen iodine laser and highly sophisticated beam control/fire control and battle management systems on a modified Boeing 747-400F aircraft to detect, track and destroy ballistic missiles in their boost phase of flight. This work analysis the ballistic missile's threat of North Korea and the flight trajectory for the SCUD missile that is cut-off by the ABL. From this analysis the possibility of the ABL applications to the Korean missile defense is presented.

이스라엘의 미사일 방어체계인 Arrow 체계는 미국과 이스라엘 간 전략적 협력관계를 통해 개발되었다. 미국 레이건 행정부의 전략방위구상(Strategic Defense Initiative, SDI) 연구에 이스라엘이 1986년에 협력함으로써 전술탄도미사일 방어체계 개발이 시작되었고, 두 차례의 획기적인 성능개량을 통해 현재 Arrow 3까지 개발되어있다. 주변국으로부터 탄도미사일 위협을 직접적으로 받고 있고, 전장의 종심이 짧은 이스라엘의 지정학적 환경에 맞도록 개발되고 지속적으로 업그레이드되고 있는 Arrow 미사일 방어체계의 개발 사례는 한반도 환경에 적합한 탄도미사일 방어체계를 구축함에 있어 모범적 사례가 될 수 있다.
