Satellite Air-defence Warning System receives the aircraft/ballistic track information and air defense control command obtained from Master Control & Reporting Center (MCRC) and Air Missile Defence Cell (AMD Cell) Systems. It consists of terminal and control system to propagate track information and air defense control command control via the military satellite communications. In this paper, there were described track information, air defense control command, the frame structure of modem to transmit a voice information and modulation/demodulator design, network synchronization methods via the satellite network.

기지방어, 대공방어 그리고 화생방방호 모델은 공군의 지상 작전 모델로써 참가 노드간 음성통신 중심의 체계로 설계되어 있어 정확한 의사전달에 문제가 있다. 이러한 문제를 해결하기 위해 최근 국방 분야에서는 데이터통신 기술을 이용하여 지휘통제 능력을 향상시키고 있다. 본 논문에서는 데이터통신에 기반한 차세대 기지방어작전 모델을 통해 기지방어 임무 성능향상을 극대화할 수 있는 새로운 모델을 제안한다. 현재까지 연구된 논문을 참고하여 새로운 모델을 개발하였고, 제안한 기지방어작전 모델을 비행기지내에 기존 정비통제용으로 구축되어 있던 와이브로 네트워크상에서 적용하여 실제실험을 하였다. 새로운 기지방어작전 모델의 분석 및 실험 결과 본 논문에서 제안한 모델이 성능개선에 효과가 있다는 결론에 도달한다.

Threat evaluation is a process to estimate the threat score which enemy aerial threat poses to defended assets. The objective of threat evaluation is concerned with making an engagement priority list for optimal weapon allocation. Traditionally, the threat evaluation of massive air threats has been carried out by air defence experts, but the human decision making is less effective in real aerial attack situations with massive enemy fighters. Therefore, automation to enhance the speed and efficiency of the human operation is required. The automatic threat evaluation by air defense experts who will perform multi-variable judgment needs formal models to accurately quantify their linguistic evaluation of threat level. In this paper we propose a threat evaluation model by using a fuzzy rule-based inference method. Fuzzy inference is an appropriate method for quantifying threat level and integrating various threat attribute information. The performance of the model has been tested with a simulation that reflected real air threat situation and it has been verified that the proposed model was better than two conventional threat evaluation models.

In the previous paper, we presented a new guidance law for a missile during boost phase. Thus, this paper deals with the guidance law for a missile after the thrust cutoff against an accelerating and turning target. It is essentially based on the concept of proportional navigation. Some simulation studies were performed using a three dimensional mathematical model of an air-to-air missile and the effectiveness of the guidance law presented was shown.

Recently, China & Japan have expanded their responding ADIZ(Air Defence Identification Zone) to implement each Government's maritime policy and to project their Air Power in preparation for maritime provocation & contingency, especially over the piled area where East Asia countries have claimed to have maritime jurisdiction one another. So this is to guide the Development Option for Korea Air Defence Identification Zone to cope with the maritime intentions of the neighboring countries, considering the international law for ADIZ, the maritime policy and the maritime sovereign & jurisdiction area of the Republic of Korea, etc.

In this paper, air-defense simulation model, called "DADSim", will be introduced. DADSim(Distributed Air Defense Simulation Model) was developed by Modeling&Simulation Lab of K.N.D.U.(Korea National Defence Univ) Weapon Systems Department. This model is an analysis-purpose model in the engagement-level. DADSim can simulate not only the global air-defense or Korean Peninsula but also the local air-defense or a battle field. DADSim uses the DTED(digital terrain elevation data) LeveII it for the representation of peninsula terrain characteristics. The weapon systems cooperated in the model are low/medium-range missile systems such as HAWK, NIKE, SAM. DADSim was designed in the way of object-oriented development method, implemented by C++ language. The simulation view is an event-sequenced object-orientation. For the convenience of input, output analysis, GUI(Graphic User Interface) of menu, window, dialog box, etc. are provided to the user, For the execution of DADSim, Silicon Graphic IRIX 6.3 or high version is required. DADSim can be used for the effectiveness analysis of­defence systems. Some illustrative examples will be shown in this paper.

There has been no systematic accumulation in the aircraft weight data even though those are crucial in the full life-cycle weight and balance program of aircraft. Companies, government agencies, and the Korea Air Force have been controling the data separately. The lack of communication between these institutes prevented the mutual use of the data. This study deals with a SE model-based weight and balance program development process for the full life-cycle weight and balance control of aircraft which enabled the efficient and mutual use of the weight data from the various institutes.

본 논문에서는 금속 연소관, 단열 고무 그리고 내열 복합재로 구성된 연소관 조립체의 접착 체결 상태를 확인하기 위해 변형률, 음향방출 신호 그리고 초음파 시험자료를 이용한 비파괴 시험 방법이 제시되었다. 또한 내압 상태에서 연소관 조립체의 각 계면 접착 상태를 정량적으로 평가하기 위해 유한요소 해석이 수행되었다. 공압 시험 중 계측한 변형률 값과 음향방출 신호 상관관계 연구를 통해 연소관 조립체의 접착 건전성 평가가 가능했다. 그리고 연소관 조립체의 여러 접착 계면 중 첫 번째 계면인 연소관과 고무간의 접착은 초음파 방법으로 분류하였다. 이러한 연구를 통해 연소관 조립체의 모든 접착 계면은 1) 초기 완전 미접착, 2) 공압 시험 중 완전 접착 분리, 3) 공압 시험 중 부분 접착 분리, 4) 완전 접착 등 4가지 형태로 분류 및 검출되었다.

A scheduled airlift is the most critical part of the air transportation operations in ROK Air Force. The military cargo-plane routing problem is a PDPLS (pickup and delivery problem in which load splits and node revisits are allowed). The cargo which is transported by a military cargo-plane is measured in pallet. The efficiency of pallet needs to be considered with respect to its volume and weight. There are some guidelines about orders of priorities and regulations in the military air transportation. However, there are no methodologies which can raise the efficiency of flight scheduling using Operations Research (OR) theories. This research proposes the effective computing methodology and the related heuristic algorithms that can maximize the effectiveness of the path routing model.
