摘　　要：由风、雨、舰船、海洋生物以及工业等因素形成的海洋环境噪声,是海洋中永恒存在的声场,包含频段丰富。无论是在水下目标的主动探测还是被动探测过程中,海洋环境噪声都被认为是水声信道中的干扰因素。但海洋环境噪声包含诸多水体、海面、海底和海洋生物等信息,可以通过反演获取海水、海底等各种信息。概述了国内外基于海洋环境噪声声成像的发展现状,并预测了该领域技术发展趋势。基于海洋环境噪声进行的水下目标探测,在探测开发海洋资源、维护国家主权和国家海洋环境安全等方面具有重要意义。The ocean ambient noise caused by wind,rain,ships,halobios and industries is an eternal sound field in the ocean,which contains rich frequency bands.Whether in the process of active or passive detection of underwater targets,the ocean ambient noise is considered as the interference factors in the underwater acoustic channel.However,the ocean ambient noise contains a lot of information of water body,sea surface,seabed,halobios,etc.,which can be used to obtain information of the seawater,seabed,etc.by inversion.In this paper,the development status of acoustic imaging based on ocean ambient noise at home and abroad is summarized,and the technical development trend in this field is predicted.Underwater target detection based on ocean ambient noise has great significance in detecting and developing ocean resources,and safeguarding national sovereignty and national marine environmental security.
