| 摘 要： | 基于声剖选取引起的深度误差模型,利用实测数据,分析比较了不同选取方法对测深结果的影响。通过仿真计算,对相邻时刻声剖点的平均声速差值与深度、波束角、断层差值的关系进行了阐述,提出了通过确定相邻声剖点平均声速差值来确定声剖密度的方法,对实际工作有一定的参考价值。

| Abstract: | Based on the model of depth error caused by selecting a reference sound profile to substitute the real sound, and using the measured data, the results of depth survey are analyzed and compared. Through simulation calculation, the relation of difference of average sound between neighboring position with depth, beam-angle and difference of depth in same position is described, and the method of determining the density of sound velocity is advanced through determining the difference of average sound between neighboring position, which can do some help for practice. |
