摘要

摘要: 为了提高水下声学滑翔机水中目标探测能力, 更好地开展矢量水听器在水下滑翔机上的应用, 文中通过在消声水池对现有“海燕-II”水下滑翔机进行的自噪声测试试验, 定量分析了4种不同工况下平台噪声对矢量水听器各通道接收信号的影响, 由试验结果可知: 水下滑翔机上集成的矢量水听器接收信号会受到严重的平台近场噪声干扰, 特别在500 Hz以下的低频段, 平台噪声对矢量水听器矢量通道的影响较大; 在40 Hz频点处, 由于航向调节机构工作对矢量水听器矢量通道具有最大58 dB的谱级升高。针对水下滑翔机平台噪声测量结果, 从5方面进行了减振降噪处理和优化, 测试结果表明, 平台优化后较之前由航向调节机构对矢量水听器产生的噪声干扰大幅降低, 但在200 Hz以下的低频段, 航向调节机构工作对矢量水听器矢量通道仍具有较大的噪声干扰。所得结论可为水下声学滑翔机在进行水中目标探测时的频率处理范围选择提供参考。

Abstract: A self-noise test was conducted on the Petrel-II underwater glider in an anechoic pool to improve the application of vector hydrophones to underwater gliders. The influences of platform noise on the received signals of each channel of the vector hydrophone under four conditions were analyzed quantitatively. The results show that the signal received by the integrated vector hydrophone on the underwater glider is critically interfered by the near-field noise of the platform because the platform noise greatly affects the vector channel of the vector hydrophone particularly in the low frequency range below 500 Hz. At the 40 Hz frequency point, the maximum spectral level of the vector hydrophone’s vector channel is increased to 58 dB because of the course adjustment mechanism. According to the noise measurement results of the underwater glider platform, the vibration and noise reduction and the optimization are performed in five aspects. Test results show that the noise interference generated by the course adjustment mechanism on the vector hydrophone is greatly reduced after platform optimization. However, the course adjustment mechanism generates significant noise interference on the vector channel of the vector hydrophone in the frequency range below 200 Hz. This study may provide a reference for the selection of frequency processing range of underwater acoustic gliders in underwater target detection
