초록
본 연구는 수동 소나의 방위 정보만으로 잠수함을 추적하는 두 무인 수상정의 협력 기동 명령 생성을 위한 다중 에이전트 강화학습 기법을 제안한다. 입자 필터로 표적 상태를 추정하고, 강화학습으로 목표 거리와 유리한 관측 기하를 유지하는 제어 명령을 생성하였다. 시뮬레이션을 통해 제안한 기법의 성능을 검증하였다.
Abstract
This study proposes a multi-agent reinforcement learning method for generating cooperative maneuver commands for two unmanned surface vehicles tracking a submarine using bearing-only passive sonar measurements. A particle filter is used to estimate the target state, while reinforcement learning generates control commands to maintain the desired standoff distance and favorable observation geometry. The performance of the proposed method is validated using simulations.
