摘要
高分辨率测深侧扫声纳系统(HRBSSS)是一种用于获取海底微地形地貌的声学探测设备。在简要介绍其工作原理、主要误差源、数据处理与偏差校准方法的基础上,针对声纳自身与整个系统两方面确定了各自的测深精度评估方法。最后以DTA-6000声学深拖系统上的HRBSSS为例,对其外场实验测深数据精度进行了评估。结果表明,HRBSSS声纳的测深精度在250m×2覆盖范围内符合IHO S-44特级标准,受传感器误差和界面影响,浅水条件下系统测深精度在水平距离113m内符合IHO S-44特级标准。
High-resolution bathymetric side-scan sonarsystem （ HRBSSS ） is a kind of acoustic detection equipment forthe micro-topography of seafloor. This paper briefly introduces the working principle, the main error sources,the data processing and error calibration method of HRBSSS at first.On this basis, an accuracy assessment method including one part for the sonar itself and the other for the whole system is determined.Then, with the field experiment data,the sounding accuracy of the HRBSSS on DTA-6000 acoustic deep tow system is assessed,and the results show that the accuracy of sonar is satisfied with the IHO S-44 special order within the coverage of 250m×2,while the coverage for the same accuracy of system is 113m in the shallow water condition due to the sensor bias and surface effect.
