This paper describes the utility of satellite sensors of the missile defense system using the estimation theory. The inherent flight characteristics of the missiles give the limitations in the response time and the countermeasures. In this point, the early warning and surveillance satellites are important. Using the Extended Kalman Filter, it is analysed LPU and MLU in DSP and SBIRS satellites, and presented the quantitative uncertainties of state estimates of non-rotational DSP compare to the rotating one.

한국의 TMD 참여문제는 실효성 문제, 경제적인 문제, 기술적인 문제 등으로 볼 때 유보하는 것이 바람직하다고 생각된다. 따라서 북한의 탄도 미사일에 대한 방어체계 구축은 동맹국의 TMD 체계와 상호 운용성을 보장할 수 있으며, 주변국으로부터 군비 확충에 대한 의심을 불식시킴과 동시에 한국적 여건에 가장 적합한 미사일방어체계(KAMD:Korea Air and Missile Defense)에 대한 개념연구의 선행이 필요하다.

In most positioning and allocation practices, many mathematical models are proposed in various fields. The set covering (SC) problem has many practical applications of modeling not only real world problem but also in military. As our air defense weapon systems are getting older and declining the performance, new plans far acquisition of high-tech air defense weapon system are being conducted. In this paper we established simulation model for optimal allocation of KDX which carries new missile defense weapon system by using partial set covering considering both attacker and defender side. By implementating simulation model, we assess the available scenarios and show the optimal pre-positioning of KDX and interceptor's allocation. Furthermore, we provide a variety of experiments and extensive scale sized situations for Korea Indigenous Missile Defense (KIMD) and support decision-making for efficient positioning of unit.

For a lower tier defense, the distance between a launcher and an engagement control station is quite important to estimate the proper defense area and to effectively arrange missile launchers. In this paper, we have analyzed an effectiveness of anti-ballistic missile launcher arrangement for the lower tier defense against the ballistic missile. The operation concept, specific configuration and aerodynamic characteristics of the ballistic missile such as SCUD-B/C, Nodong are considered in order to develop a realistic engagement simulation. The diverse engagement results through numerical simulations are provided to conduct the effectiveness analysis of anti-ballistic missiles.

It is important to operate a limited number of interceptors effectively to counter ballistic missile threats. The existing interceptor operating method determines the number of interceptors according to the level of TBM (Theater Ballistic Missile) engagement effectiveness applied to a defended asset. It can cause either excessive interceptor waste compared to the intercept probability or the intercept probability decrease. Thus, interceptor operating method must be decided considering the number of ballistic missiles, intercept probability and cost. This study proposes a mathematical model to improve the existing interceptor operating method. In addition, the efficiency indicator is proposed for trade-off between intercept probability and cost. As a result of the simulations, the mathematical model-based interceptor operating method can achieve better results than the existing interceptor operating method.

North Korea has various ballistic missiles from short range to long range such as inter continental ballistic missiles. Short range ballistic missiles such as SCUD series are threatening to Korea peninsula. Therefore Korea is constructing various missile defense systems to protect country. Parameters influencing the received power from the target to the radar are transmitting power, antenna gain, carrier frequency, RCS(Radar Cross Section) of target and distance from radar to target. Especially, RCS and distance from target are not radar performance defined parameters but external parameters. Therefore radar deployment position that large RCS can be observed and target to radar distance should be considered in parallel to improve target detection probability. In this paper, RCS pattern of SCUD-B ballistic missile is calculated, received power is analyzed based on radar deployment position during ballistic missile trajectory and methode for optimum radar deployment position to improve target detection probability is suggested.

Radar Cross Section(RCS) is very important factor to detect target by radar. Even if the same target, RCS value is significantly different according to the direction facing the radar. Therefore, it is advantageous to place the radar, where RCS is larger to increase the probability of detecting a target with a radar. North Korean ballistic missiles are major threat to our security, ballistic missiles should be detected early and traced for ballistic missile defense. In this paper, it is analyzed that ballistic missile's RCS characteristics and trajectory and proposed a way of radar deployment to improve the detection probability of ballistic missile.

광속의 레이저 무기가 실용화될 경우 방공 및 미사일 방어, 각종 곡사화기 공격에 대한 방어 등에 매우 획기적이라는 점을 이미 선진국에서 인지하고, 막대한 투자를 하고 있다. 특히 화생방 무기를 장착한 미사일 공격시 고고도 및 우주에서의 요격을 통해 그 효과를 상당히 무력화 시킬 수 있다는 점은 매우 매력적이라 할 수 있다. 이러한 점에 비추어 볼 때, 레이저 무기 개발에 대한 관점을 군이 아닌 국가적인 차원에서 접근하여야 할 것으로 생각된다.

보스니아 내전 지역을 정찰비행 중이던 미 해군 F/A-18F 슈퍼 호넷을 향해 갑자기 지대공 미사일 공격이 가해진다. 조종사는 미사일의 추적을 뿌리치기 위해 모든 방어 장비를 총 동원해 회피 기동을 펼치지만 결국 적진 한 복판에서 격추되고 만다. 지난 2002년 1월 개봉한 영화 에너미 라인스(Behind Enemy Lines) 초반에 등장하는 장면이다. 영화에서 묘사된 것과 같이 미사일은 피아를 불문하고 가장 강력한 공격무기이자 가장 대응하기 까다로운 무기다.

The North's short-range projectiles and missiles are the Iskander-class missiles of the S-300 series, with a range of 270-420 kilometers and an altitude of 40-50 kilometers, making it very difficult to respond with South Korea's detection radar or striking weapons. The North's handling of the Seoul sea of fire also makes it very urgent for the South to deploy the weapons to power or introduce them as soon as possible, as it can identify its intention to strike the Seoul metropolitan area by equipping such short-range rockets and missiles with nuclear or chemical weapons. We will be prepared to prep are for reckless provocations by securing our own technology by continuously developing the Korean missile defense system and striking system, Kill Chain, which is designed to defend short-range missiles in the long-term, and securing our own technology.
