The invention discloses an underwater vehicle, a seabed near-bed surface flow field measurement method and an underwater coordinate positioning method in the ocean engineering field, a plurality of underwater vehicles are used to form a measurement array so as to obtain flow velocity data of a plurality of point locations of a target sea area at the same time, thereby obtaining the flow field data of the measurement area at the time; transmitting and receiving underwater acoustic communication information between every two underwater vehicles, wherein the content of the underwater acoustic communication information comprises the serial number of the underwater vehicle for transmitting the information, the serial number of the underwater vehicle for receiving the information and the time for transmitting the information; according to the sending time and the receiving time of the underwater acoustic communication information and in combination with the local seawater sound velocity, the flow velocity component of seawater between the two underwater vehicles in the connecting line direction of the two underwater vehicles is calculated; if a plurality of underwater vehicles form a planar array, the flow velocity of seawater near the central underwater vehicle along the array plane can be obtained according to the seawater flow velocity component in the direction of the connecting line between any central underwater vehicle and the surrounding underwater vehicles.

    本发明公开了海洋工程领域的一种潜航器、海底近床面流场测量方法及水下坐标定位方法,使用多个潜航器组成测量阵列,以在同一时间获得目标海域多个点位的流速数据,从而获得该时间、该测量区域的流场数据;使潜航器两两之间相互收发水声通信信息,水声通信信息的内容包括发送信息的潜行器编号、接收信息的潜行器编号以及发送信息的时间;根据水声通信信息的发出时间和接收时间,并结合当地海水声速,计算得到两个潜航器之间的海水沿两机连线方向的流速分量;若多个潜航器组成平面阵列时,根据任意一个中心潜航器与周围潜航器之间连线方向的海水流速分量,可获得该中心潜航器附近海水沿阵列平面的流速。
