This paper introduces the research on supervision technology of bathymetric survey , which has been applied successfully to the acceptance survey of dredging project 摘要介绍水深测量监理技术方面的研究及相应技术在疏浚工程验收测量中的成功应用。
Today , enough soundings are available to enable a relief map of the atlantic to be drawn and we know something of the great variety of the sea bed ' s topography 现在已有足够的水深测量数据来绘制一张大西洋洋底地形图，而且我对海底地形的千变万化也有了一定的了解。
The underwater topographic survey in lake dianchi employed the dual - frequency gps with rtk technology , which type is american trimble 4700 , for horizontal positioning f and the type of the fathometer is wuxi haiying sdh - 13d ; the navigation software : the south 5 . 0 对滇池水下地形测量外业数据的采集，平面定位采用美国trimble4700双频gps接收机；水深测量采用的测深仪为无锡海鹰sdh ? 13d ；导航软件为南方公司的导航5 . 0版。
At the basis of designing underwater geomorphological measurement system concrete plan , this dissertation makes study and analysis on its measuring depth of water sonar system and dynamic global position system . this dissertation simply and thoroughly introduces the state of underwater acoustic transducer and array . it covers the basic situation , the study benefits , the classification and role , analyses the performance index , designs the performance parameter relating to themselves performance synthesis and sonar equation 论文在制定水下地貌测量系统技术方案的基础上，论述了该系统中的水深测量声纳系统和动态定位系统( dgps ) ，分析了水声换能器及基阵的性能指标，确定了换能器及基阵的主要性能参数。
The results from the processing of h / hcs - 017 multibeam echo sounder data has shown that this combination method can detect a wide horizontal range up to 75 angle to the vertical and obatain the so called ultra - wide coverage detection the precision of measurements has been given under 0 . 3 % generally when surveying angle is under 60 ? angle in simulation data , while under 0 . 5 % for deep sea detection in the same angle range therefore this method accomplishes high precision measurements 在海试数据处理中，将wmt法和相位差法联合使用。 h hcs - 017海试数据的处理结果表明相位差海底检测方法在浅海时可以处理到75的边缘波束，实际上已经实现了水深测量的超宽覆盖。测量精度在仿真时小于60工作范围一般小于0 . 3 ；在该角度工作范围，深海数据也达到了0 . 5 ，实现了高精度测量。
