中文摘要
水声是人类迄今为止所知道的唯一能在海洋里远距离传播的能量形式。其他的物理媒介，如可见光、电磁波、激光等在海水里传播时会很快衰减掉，因而无法传向远方。凡是利用水声能量进行观测、通讯的系统，均称为声呐系统。水声信号处理和声呐技术是一门发展迅速、需求推动力强大、应用前景异常广阔的学科。在声学领域的众多分支学科中，没有其他学科像水声学那样，其发展受着战争需求的推动。反过来，水声学的发展又为水下战武器装备的研制和创新注入活力。文章介绍我国改革开放40年来水声信号处理和声呐技术领域的研究进展和发展前景。包括水声信号建模、声场匹配、海洋波导和内波现象的探索与研究、水声信道的时/空相关特性、水下目标辐射噪声的提取及检测技术、高分辨力水下成像技术，以及水下语音、图像传输和抗干扰技术。文章还介绍了我国“863”计划海洋监测主题所取得的成就。提出了我国水声信号处理和声呐技术领域的发展前景，包括深海声学、北极声学、安静型潜艇辐射噪声检测、水下-水面-空天一体化信息获取和融合技术等，以及在建设海洋强国战略中不可替代的独特作用。
英文摘要
The advances and prospect of underwater acoustical signal processing and sonar technology in China during last 40 years is introduced, including the theory and experiment of underwater acoustical signal modeling, technique of acoustical field matched, exploration and study of ocean waveguide and internal wave phenomena, information acquisition and processing of acoustical vector field, research work in time/space correlation performance of underwater acoustic channel, extraction and detection technique of radiated noise invariant feature of underwater target, high resolution image sonar technique and anti-interference transmission technology of underwater speech and image. The theoretical study achievement and the application of these technologies produce a series technology innovation in sonar design, such as large aperture linear towed array Sonar for long range signal detection, Synthetic Aperture Sonar (SAS) of high resolution image sonar, high fidelity real time voice communication sonar, passive ranging sonar, acoustic-guided torpedo, and multiple purpose surface and submerged buoy. Some of achievements, which was carried out in past 863 Program in marine area are introduced. The prospect of underwater acoustical signal processing and sonar technology is discussed in this paper, including deep sea acoustics, Arctic acoustics, radiated noise detection of quiet submarine, integrated information acquisition and data fusion technique in the field of underwater-sea surface-space. The special and irreplaceable important role of these technologies in constructing maritime power country is given.
