Simulation Research on Influence of Internal Wave on Multibeam Echo Sounding
为了研究内波对多波束测深的影响,通过对内波建模,分别对四个区间的声线跟踪情况进行了研究分析.在此基础上,推导了针对曲线型梯度结构的声线跟踪模型,并根据该模型进行了仿真分析.仿真简单模拟了采用常梯度声线跟踪模型对曲线型梯度结构声速剖面进行声速改正的声线跟踪过程.采用仿真数据绘制了声线跟踪前后的声线示意图,并对归算前后的波束脚印位置进行了比较分析.仿真结果说明内波会给多波束的边缘波束带来大量尖峰状的浅点,而这些浅点难以用传统的声速改正模型消除.推导的…查看全部>>
In order to study the influence of internal wave on multibeam echo sounding,the internal wave modeling is used to analyze the acoustic ray-tracing in four sections in this paper.On this basis,the acoustic ray-tracing model for the curved gradient structure is deduced,and the simulation analysis is carried out according to the model.The simulation process is used to simulate the sound velocity ray-tracing process of the velocity gradient of the curved gradien…查看全部>>
