摘要
介绍了我国自主设计和研制的深水声学拖曳系统,它的最大工作水深4 000m,安装有高分辨率测深侧扫声纳,可在近海底工作获得高分辨率的海底地形地貌和温盐深等数据。它的测深覆盖范围600m,侧扫覆盖范围800m,垂直航迹分辨率5 cm,最小可检测高度10 cm,测深分辨率高于目前的多波束测深系统。该系统已进行了湖试和海上锚泊试验。该系统的研制成功将对开展大陆架勘查,探测和开发国际海底资源发挥重要作用,拖曳系统中高分辨率测深侧扫声纳还可装船安装,在大陆架水域进行高分辨率海底地形地貌测绘。
This paper describes the towed deep water acoustics system developed in China. The operating depth of the system can reach up to 4000m. With high resolution side scan sonar, it can obtain high resolution submarine relief feature, temperature-salinity-depth data and so on in offshore submarine. The sounding coverage is 600m, the side scanning coverage is 800m, the resolution of vertical track is 5cm, the least detecting height is 10cm and the sounding resolution is higher than that of many multi-beam sounding systems. The system has been tested in lake and at sea. The development and achievement of the system will play an important role in continental shelf exploration and the international exploitation of submarine resource. The high resolution side scan sonar of the system can also be mounted in vessel and carries out high solution surveying of submarine relief in continental shelf waters.
