摘　　要：为实现潜艇辐射噪声的实时监测,在介绍目前世界各国海军常用潜艇噪声舰载检测设备的基本特点和用途的基础上,分别研究了采用加速度传感器提取潜艇主要噪声源特征频谱的方法、基于状态监测的自噪声水听器阈值显示与设定方法以及基于远场测量的自噪声水听器阈值设定方法。结果表明,该研究可达到提取潜艇主要噪声源特征谱和设定自噪声水听器阈值的目的,能为潜艇实时监测潜艇辐射噪声提供依据。In order to monitor the radiation noise of submarine in the real time is come true, on the basis of basic characteristics and uses of monitoring submarine noise on-board equipments which are often used in worldwide navy were introduced, method of extracting characteristic frequency spectrum of main noise sources for submarine was studied by use of acceleration sensors, and then displaying and setting threshold of self-noise hydrophone was studied based on the condition monitoring, and setting threshold of self-noise hydrophone was studied based on far-field measurement. The results demonstrate that the characteristic spectrums of main noise sources from submarine can be picked up and threshold of self-noise hydrophone can be set by use the method of this paper, which can provide the base for monitoring the radiation noise of submarine in the real time.
