Abstract

This paper deals with a beam scheduling method in fighter interleaving mode. Not only the priority of tasks but also operational requirements that air-to-ground and air-to-air search tasks should be executed alternatively are established to maximize high-quality of situational awareness. We propose a real-time heuristic beam scheduling method that is advanced from WMDD to satisfies the requirements. The proposed scheduling method is implemented in a simulation environment resembling the task processing mechanism and measurement model of a radar. Performance improvement in terms of task delay time is observed.

본 논문은 전투기 레이다 공대공, 공대지 동시 운용 모드에서의 빔 스케줄링 방법을 다룬다. 양질의 전장 상황 인식을 위해 임무들의 우선순위와 더불어 공대공, 공대지 탐색 임무가 교차로 수행되어야 한다는 요구조건을 정립하였다. 그리고 이를 만족하기 위해 WMDD를 개선한 실시간 휴리스틱 빔 스케줄링 방법을 제안한다. 제안된 스케줄링 방법은 실제 레이다 임무 처리 메커니즘 및 측정 모델이 구현된 시뮬레이션 환경에서 비교 분석하였으며 임무 지연시간 관점에서의 성능 향상을 확인하였다.
