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 deals with supersonic air-breathing missile system. A supersonic air-breathing missile system has very complicated and incoherent thrust characteristics with respect to outer and inner environment during operation. For this reason, the missile system has many maneuver constraints and is allowed to operate within narrow flight envelope. In this paper, trajectory optimization of the missile is accomplished. The trajectory optimization problem is formulated as a discrete parameter optimization problem. For this formulation, Legendre Pseudo-Spectral method is introduced. This method is based on calculating the state and control variables on Legendre-Gauss-Lobatto (LGL) points. This approach helps to find approximated derivative and integration quantities simply. It is shown that, for this trajectory optimization, trend analysis is performed from thrust characteristics on various conditions so that the trajectory optimization is accomplished with fine initial guess with these results.

Recently, the development of military system is focused on Network Centric Warfare. But, there is no deployed Command and Control System for Missile System in the country. Therefore, Command and Control System for Missile System was simulated to predict feasibility for the future development in this paper. The contents of the design and implementation for simulated system are described in details. Besides, a method for avoiding collisions in 1:N radio communication environment is proposed as the future work. The simulated system in this paper will be a help to developing Command and Control System for Missile System in the future.

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.

In order to respond to the ballistic missile threat of North Korea, the ROK military is constructing a multi-layered defense that can minimize the vulnerability of single-layered defense. Accordingly, it is necessary to study an operation plan which can maximize the intercept rate of a multi-layered defense system. And to study the operation plan of the Korean missile defense system, it must be considered that the operational environment of the Korean military and the effects of the strategic strike system. Therefore, this study proposes a simulation model that reflects the characteristics of the Korean missile defense system and analyzes four interceptor missile operation plans. The simulation result indicates that a high intercept rate can be achieved in various situations by comprehensively considering the ballistic missile threat estimate, interceptor missile reserve, and the strategic strike system effect.

Since V-2, the first ballistic missile was developed during world war II, ballistic missile threat is increasing consistently due to science technology progress. United States is constructing and operating BMDS(Ballistic Missile Defense System) to defend homeland and allies. Various Interceptors will try intercept ballistic missile detected by sensors at boost phase, midcourse phase or terminal phase. THAAD(Terminal High Altitude Area Defense) is intercept system that intercept ballistic missile at high altitude of terminal phase. In this paper, concept of U.S. BMDS, and operational and technical characteristics of THAAD is surveyed and described.

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.

Modal parameters of a structure are the important factor to control the missile maneuver. In general, a dummy structure is used for the modal test of missile structure instead of the real warhead and propellant because there may be the danger of a explosion by the electric shock of test equipment, such as the exciter and the power amplifier. However, the modal testing of a real missile structure is required to acquire the modal parameters and to analyze the missile performance accurately. The new test system and technique are developed to get rid of the danger and secure the safety during the testing. This test system is made of with the computer network system and controlled remote from test site. Using His new test system, the modal test of real missile structure is performed successfully and its validity is proven.

The Arrow system, an Israeli missile defense system, was developed through a strategic partnership between the United States and Israel. Israel's cooperation with the Strategic Defense Initiative(SDI) research of the Reagan administration in the United States began in 1986 with the development of a tactical ballistic missile defense system and two increasingly improvements to Arrow 3. It could be a moral lessen to developing Korean Ballistic Missile Defense System because Israel's Geopolitical environment is similar to Korean peninsula.

In this paper, the electromagnetic compatibility (EMC) test standard is described, and the purpose and test configuration for the electromagnetic susceptibility (EMS) test of the missile component and the missile system are confirmed. The test configuration and specifications are suggested by the configuration of the missile component and the missile system based on the US military standards MIL-STD-461F and MIL-STD-464C, and explained that the ungrounded state, the final operating state of the missile component and the missile system, was constructed. In addition, the methods for checking the steady state and the points to be considered during the immunity test were introduced.
