title = "Research on the high-precision acoustic autonomous navigation technique of UUV based on sound ray revision",
abstract = "In an underwater channel, sound rays often propagate along a bended curve for the existence of gradient in ocean sound speed, which would cause great error in acoustic navigation. The sound ray revision must be considered carefully to get high-precision acoustic autonomous navigation of UUV. In this paper, the concept of effective sound velocity is adopted to revise sound ray. An acoustic navigation method based on the correction of slope distance is proposed and the application of effective sound velocity under different sound speed gradients in acoustic navigation is investigated. Simulation shows that the correction can improve the precision of navigation effectively.",
