| 摘 要： | 针对声速剖面在横向空间上的低密度、分布不均匀导致水深测量误差的问题，提出了一种容易实现且有效的思路，采用分层取样、空间插值的方法，在后处理过程中人为地增加声速剖面的数量，使其密度足够大、分布更均匀，达到改善声速改正的效果和提高多波束测深精度的目的。

| Abstract: | There are some errors in water bottom survey cause of the low density and uniformity in the distribution of sound velocity profile. The idea could be easily carded out and has improved the sound velocity correction effect and multi-beam survey precision. Using the method of sampling in layer and interpolation in space, the velocity profiles is increased to enough density and more balanced distributing by post processing. |
