The invention discloses a ship underwater noise tracking and monitoring device and method. The method comprises the following steps: 1) installing a monitoring device on a ship; 2) keeping the ship in a stop state in the navigation channel, monitoring environmental noise in the navigation channel by each hydrophone, and recording an environmental noise signal by a data acquisition device; 3) according to the test working condition, the ship equipment is normally started or operated; (4) the ship normally sails in the navigation channel, and the data acquisition equipment records sound wave signals measured by the hydrophone; and 5) based on the channel environment noise monitored in the step 2), removing the environment noise from the sound wave signal measured by each hydrophone, and then analyzing and processing all the noise-reduced underwater radiation noise signals of the sailing ship. According to the invention, the tracking measurement hydrophone array is arranged around the ship, navigation monitoring is carried out under various actual working conditions of the ship, a real ship-around flow field around the ship during navigation is provided, and the accuracy of a monitoring result is high.

    本发明公开了一种船舶水下噪声跟踪监测装置及方法,该方法包括以下步骤:1)将监测装置安装到船舶上;2)保持船舶在航道中处于停止状态,各个水听器对航道中环境噪声进行监测,数据采集设备记录环境噪声信号;3)根据测试工况,船舶设备正常开启或运行;4)船舶正常航行于航道中,数据采集设备记录水听器测量的声波信号;5)基于步骤2)中监测到的航道环境噪声,对每个水听器测量的声波信号去除环境噪声,再对所有降噪后的航行船舶水下辐射噪声信号进行分析处理。本发明在船舶周围布置有跟踪测量水听器阵列,并在船舶各种贴合实际的工况下的进行航行监测,具备航行时船舶周围真实的绕船流场,监测结果精确度高。
