摘要
针对目前多波束测深仪缺乏检定的情况,设计了多波束测深检定系统,并对SeaBat8101型多波束测深仪进行测深精度的检定实验,利用最小二乘原理对实验结果进行拟合。实验结果表明,被检定多波束测深精度良好,实验设计可行,可以用于多波束测深系统的多次重复性检定。
Multi-beam depth sounder systems were short of calibration. Based on this situation, the calibration system was designed. And the measurement accuracy of SeaBat8101 was calibrated by the system. The calibra- tion results were settled by least squares collocation. The results showed that the depth accuracy of calibrated multi-beam sounder was so fathful that the method could be used to calibrate multi-beam sounders.
