Para localizar uma fonte de ondas desconhecida em ambientes sem linha de visão, é proposto um esquema de localização de fontes de ondas usando vários veículos aéreos não tripulados (UAVs). Neste esquema, cada UAV estima a direção de chegada (DoAs) dos sinais recebidos e a fonte de onda é localizada a partir dos DoAs estimados por meio de estimativa de máxima verossimilhança. Neste estudo, ao estender o conceito deste esquema, propomos um novo esquema de localização de fontes de ondas usando um único UAV. No esquema proposto, o UAV se move no caminho que compreende múltiplos pontos de medição e a fonte de onda é localizada sequencialmente a partir de distribuições DoA estimadas nesses pontos de medição. Em cada ponto de medição, com um algoritmo de planejamento de caminho móvel, o UAV determina o próximo ponto de medição a partir das distribuições DoA estimadas e dos pontos de medição que o UAV já visitou. Consideramos dois algoritmos de planejamento de caminhos móveis e validamos o esquema proposto através de experimentos de simulação.

Abstract: To localize an unknown wave source in non-line-of-sight environments, a wave source localization scheme using multiple unmanned-aerial-vehicles (UAVs) is proposed. In this scheme, each UAV estimates the direction-of-arrivals (DoAs) of received signals and the wave source is localized from the estimated DoAs by means of maximum likelihood estimation. In this study, by extending the concept of this scheme, we propose a novel wave source localization scheme using a single UAV. In the proposed scheme, the UAV moves on the path comprising multiple measurement points and the wave source is sequentially localized from DoA distributions estimated at these measurement points. At each measurement point, with a moving path planning algorithm, the UAV determines the next measurement point from the estimated DoA distributions and measurement points that the UAV has already visited. We consider two moving path planning algorithms, and validate the proposed scheme through simulation experiments.
