摘　　要：多波束勘测之前,为了保证多波束成果质量,需要对多波束声纳系统进行一系列设备安装校准和精度评估工作.基于在渤海湾开展的多波束海底地形地貌勘测项目,在项目勘测之前,对EM1002S与GeoSwath多波束声纳系统进行了安装校准,并对2套多波束声纳系统的测深精度进行了比较分析,通过计算得到两套系统之间的最大测深误差为-0.38 m,测深误差主要为0～0.2 m,无超限数据,结果分析显示2套多波束声纳系统的测深精度满足勘测技术要求,为我们调查工作的顺利开展奠定了良好的基础.To guarantee the quality of multi-beam sonar data, a series o{ equipment cali- brations and accuracy assessments must be done for the multi-beam sonar systems be- fore the survey. During the multi-beam surveys of seabed topography and geomorpholo- gy carried out in the Bohai Sea, two sets of multi-beam sonar systems EM1002S and GeoSwath were applied. The installation and calibration o{ the two systems were con- ducted before the survey and their sounding accuracies were compared based on the anal- ysis of the data obtained. The results show that the sounding errors range mostly be- tween 0 - 0.2m with a maximum of -0.38m and with no overrunning data, indicating that the two sets of multi-beam sonar systems can meet the technical requirements of ba- thymetric surveys.
