| 摘 要： | 多波束测深系统的声学原理和海水的不均匀性,使得声波在传播过程中发生声线的折射现象,对波束测点位置的计算带来较大误差。针对多波束数据后处理常用的几种声线跟踪方法,通过模型分析,仿真实验,对比分析得出了各个方法的优缺点,估计了各种跟踪方法的模型精度,证明等效声速法与常梯度法应用价值较高。

| Abstract: | Multibeam sounding system can provide a swath bathymetric survey,the ray will bend because of theinhomogeneity of the sea water.In this paper,some methods of ray-tracking based on equivalent sound velocityprofile are described.Through comparing and analyzing,some advantages and disadvantags of different methodsare given,and the accuracy of different models is estimated.Also,in the aspect of application,the equivalentsound velocity profile method and the invariable grad method have some advantages. |
