| 摘 要： | 本文在全面分析和总结多波束海洋测深主要误差源的基础上，提出通过相邻条带测深数据融合处理进行多波束测深系统偏差补偿方法；并提出以单波束测深数据作为控制，进一步提高多波束测深整体测量精度的数据处理方案；详细讨论了数据融合处理中的数值解算可行性和稳定性问题，相应提出了两步平差方法。本文最后使用我国自行研制的条带测深系统实测数据验证了上述方法的有效性和可靠性。

| Abstract: | Based on an analysis of the error sources in multibeam echosounding system, a method of compensating systematic errors in multibeam survey, through the data fusion of neighboring swaths, is proposed in this paper. In order to improve the accuracy of overall swath, a data fusion technique for single beam and multibeam echosoundings, using single beam survey data as a control information, is then presented. Some questions involved in solving the adjustment problem, such as its feasibility and the numerical stability, are discussed in detail, and then a two step adjustment method is suggested. Finally, a practical survey data set from a multibeam echosounding system named H/HCS 017 made in our country is used as a case study to prove the efficiency and reliability of the proposed methods. |
