초록

본 논문은 무인전투기를 위한 일대일 근접 교전 상황에서의 가상 추적점을 이용한 자율 공중 교전 법칙에 관해 기술하였다. 가상의 지연 및 선도 추적점으로 구성된 가상 추적점은 전술 교전 기동을 수행하기 위해서 도입한 것으로 각 가상 추적점은 전투기의 공력 특성과 기본 전투 기동의 선회원, 총 에너지 및 무기 거동 특성을 고려하여 생성된다. 무인전투기는 현재의 교전 상태를 기반으로 기동 전환을 위해 각 추적 기동의 확률을 평가하는 스무딩 함수를 이용해 단일의 가상 추적점을 결정하고 추적 기동을 실시하게 된다. 제안된 기법은 상용 전투기 모델과 X-Plane 시뮬레이터를 이용한 고충실도의 실시간 교전시뮬레이션을 통해 성능을 검증하였다.

This paper describes an autonomous air combat guidance law using a Virtual Pursuit Point (VPP) in one-on-one close engagement for Unmanned Combat Aerial Vehicle (UCAV). The VPPs that consist of virtual lag and lead points are introduced to carry out tactical combat maneuvers. The VPPs are generated based on fighter's aerodynamic performance and Basic Fighter Maneuver (BFM)'s turn circle, total energy and weapon characteristics. The UCAV determines a single VPP and executes pursuit maneuvers based on a smoothing function which evaluates probabilities of the pursuit types for switching maneuvers with given combat states. The proposed law is demonstrated by high-fidelity real-time combat simulation using commercial fighter model and X-Plane simulator.
