摘　　要：声学方法探测沉底及掩埋小目标在沉埋雷探测、海洋油气田管线定位等军民技术应用领域有着迫切需求及重要意义。文中概述了浅地层剖面仪、合成孔径声呐及海底三维成像系统等几种主流声学探测沉底及掩埋目标技术装备的现状及特点,分析了各自优势及存在的不足。并针对沉底及掩埋有限长管线目标探测需求,分析了低频宽带多波束声呐探测沉底及掩埋有限长管线目标的混响抑制及空间分辨能力,设计了系统的技术指标、使用方式、声探测基阵技术方案、硬件技术方案、信号处理流程、软件界面及软件处理流程,归纳总结了文中设计的低频宽带多波束声呐系统特点,在湖上完成了沉底有限长管线目标的试验验证。结果表明,低频宽带多波束声呐能可靠并有效地探测沉底管线目标。The present situation and characteristics of the acoustic detection technology and equipment for submerged and buried targets,including sub-bottom profiler,synthetic aperture sonar,and three-dimensional imaging systems,are summarized,and their problems and shortcomings are analyzed.In view of the detection requirements for length-finite submerged and buried pipeline targets,the reverberation suppression and spatial discrimination ability of the low-frequency broadband multi-beam sonar for detecting submerged and buried pipeline targets are analyzed.The tech-nical specification,usage mode,technical scheme of acoustic detection array,signal processing flow,software interface and software processing flow are designed.The characteristics of the designed low-frequency broadband multi-beam sonar are summarized.The lake trial of submerged and length-finite pipeline targets detection verifies that the low-frequency broadband multi-beam sonar can detect the submerged pipeline targets reliably and effectively.
