摘　　要：为探讨浅地层剖面声学影像形成原理,探索不同类型沉积物声学影像特征,厘清不同沉积物厚度的识别算法,采用模块化设计理念研发一套新型浅地层剖面仪室内试验平台。综合室内定位技术、浅剖试验平台尺寸合理性分析技术、直线轨道与换能器之间的固定连接技术和海底声学参数反演技术,形成一个试验高效的新型平台。通过铺设沉积物和布设障碍物,利用浅地层剖面仪进行走航测试,精确识别了沉积物的厚度和障碍物的位置。该平台可为开展理想环境下沉积物厚度和障碍物识别提供较好的测试环境,为声学海洋设备性能检测提供测试平台,也为高校学生和技术人员提供设备使用培训场所。In order to further study the formation principle of acoustic image achieved by sub-bottom profiler and analyze the acoustic image characteristics for different types of sediments and understand the recognition algorithras for the sediment thickness, designing and creating the indoor test platform system applied to sub- bottom profiler are imminent.The indoor test platform system using sub-bottom profiler is created based on the concept of system engineering and according to the principles and methods of ocean engineering design. Indoor positioning technique, dimension rationality analysis technology of the indoor test platform, fixed connection technology between the platform and linear orbit control system, and acoustic parameters inversion technique are applied to the total indoor test platform system, which has strong and efficient testing capability. Different thickness and different types of submarine sediments and obstacles are laid in the platform and underway survey is carded out using sub-bottom profiler. Test results indicatsd that identifying accuracy of the thickness of submarine sediments and position of obstacles are very high. The platform will provide an ideal test site for studying the thickness of submarine sediments and position of obstacles. It also provides a testing platform for some acoustics marine equipment, a good training place for students and technicians.
