An aircraft collision accident is a disaster that causes great losses of inventories and lives. Though a collision avoidance warning function is provided automatically to pilots in the aircrafts by the enhancement of the aircraft capability, achieving fast decision-making to escape a collision situation is a complex and dangerous work for pilots. If an in-flight collision situation is controlled by the air traffic control system which monitors all airplanes in the air, it would be more efficient to prevent in-flight collisions because it can handle the emergency before the pilot's action. In this paper, we develop the collision avoidance warning function in the air traffic control system. Specifically, we design and implement the five stages of the collision avoidance function, and propose a visualization method which could effectively provide the operators with the trajectories and altitudes of the aircrafts in a collision situation. By developing an in-flight collision warning function in the air traffic control system that visualizes flight patterns through the state transition data of in-flight aircrafts on the flight path lines, it can effectively prevent in-flight collisions with traffic alerts. The developed function allows operators to effectively select and control the aircraft in a collision situation by providing the operators with the expected collision time, the relative distance, and the relative altitude while assessing the level of alert, and visualizing the alert information which includes the Attention-Warning-Alert phase via embodying the TCAS standard. With the developed function the air traffic control system could sense an in-flight collision situation before the pilot's decision-making moment.

In this paper, we have proposed the design and implementation for efficient Command Control and Alert(C2A). Information fusion must be done for knowing the state and identification of targets using multi-sensor. The threat priority of targets which are processed and identified by information fusion is calculated by air-defence operation logic. The threat targets are assigned to the valid and effective weapons by nearest neighborhood algorithm. Furthermore, the assignment result allows operators to effectively operate C2A by providing the operators with visualizing symbol color and the assignment pairing color line. We introduce the prototype which is implemented by the proposed design and algorithm.

방공지휘통제경보체계는 작전환경에서의 적의 기습적 공중공격으로부터 우군의 부대, 시설 및 요충지 등을 방호하기 위하여, 전장의 탐지/식별센서, 경보전파/사격통제 및 타격체계를 유기적으로 결합하여 방공작전시 동시성과 통합성을 달성할 수 있는 체계이다. 방공지휘통제경보체계는 육군의 표준화된 가변형 메시지 포맷(KVMF) 메시지를 활용하여 체계 내 외부와의 통신하는데, 비트 단위의 메시지 처리가 짧은 시간동안 많이 발생하므로 메시지 처리 속도의 향상이 중요하다. 본 논문에서는 방공지휘통제경보체계의 KVMF 처리기 메시지 처리 속도 향상방안을 제안한다.
