The invention provides an underwater vehicle and an underwater positioning method and device, and belongs to the technical field of marine mechanical equipment. The underwater vehicle comprises a vehicle body and a signal processing unit; the aircraft body is provided with a plurality of cabins, and each cabin is internally provided with a movable hydrophone array element; at least three hydrophone array elements in all the hydrophone array elements are unfolded outwards from the cabin body to form a hydrophone array; and the signal processing unit receives the sound source signal received by the hydrophone array, and locates a target sound source emitting the sound source signal. According to the invention, at least three movable hydrophone array elements are arranged, when a positioning task needs to be executed, the underwater vehicle controls the at least three hydrophone array elements to expand outwards from respective cabins to form a hydrophone array, then sound source signals of a target sound source are received and processed, and the hydrophone array elements can be hidden in the cabins at other moments, so that the positioning task can be executed. Stable navigation of the underwater vehicle is guaranteed to the maximum extent, and the underwater sound source can be accurately, efficiently and stably positioned.

    本发明提供水下航行器、水下定位方法及其装置,属于海洋机械装备技术领域,水下航行器包括航行器本体和信号处理单元;航行器本体上开设有多个舱体,各舱体内设置有可活动的水听器阵元;所有水听器阵元中的至少三个从舱体向外展开后构成水听器阵列;信号处理单元接收水听器阵列接收到的声源信号,定位发出声源信号的目标声源。本发明通过设置至少三个可活动的水听器阵元,在需要执行定位任务时,水下航行器控制至少三个水听器阵元从各自舱体向外展开构成水听器阵列,进而接收和处理目标声源的声源信号,其他时刻水听器阵元可隐藏在舱体内,既最大程度保证了水下航行器的稳定航行,又能准确、高效、稳定地对水下声源进行定位。
