中文摘要:
      波浪滑翔器作为一种跨界面无人自主航行器具有独特的优势,既可以作为水下与水面通信的中继节点,又可以搭载观测设备在大洋上长期自主航行,实现长时序、大范围观测。利用波浪滑翔器搭载声学负载组成声学探测节点,由多个节点按一定的轨迹运行组成特殊接收阵型可以提高水下目标检测概率。文章利用波浪滑翔器搭载自容式水听器在青岛近海开展了海上试验,评估了波浪滑翔器的本体噪声特性,验证了其搭载声学负载的可行性。试验过程记录了环境噪声、波浪滑翔器运行过程中产生的自噪声以及附近海域的哺乳动物的声信号。通过分析波浪滑翔器运行原理以及岸上实际模拟,给出了波浪滑翔器不同本体噪声产生的机理,在此基础上给出了消除波浪滑翔器机械噪声的建议,并给出了合理的声学负载拖曳方案。
英文摘要:
      The wave glider is a new unmanned ocean vehicle crossing sea-surface and underwater. It could be used as a mobile station to provide real-time relay communication between underwater equipment and shore station. As its propulsion power is almost unlimited, long term oceanographic observation could be deployed by the wave glider with different sensors in a large area. A wave gilder integrated with acoustic payloads can be taken as an acoustic sensor. Detection capability can be improved when several acoustic sensors move along the planned trajectory that forms a large receiving array. A wave glider towed self-contained hydrophone is deployed in the offshore of Qingdao. Ambient noise, wave glider generated noise and bioacoustics signals are recorded. Self-noise characteristics of wave glider are analyzed with these recorded data. Noise generating mechanism of wave glider is analyzed according to the operational principles of wave glider and the experimental data recorded underwater and in laboratory. Some advices to reduce the mechanical noise of wave glider based on the noise analysis are proposed, and a reasonable towing structure of acoustic payload is given.
