摘要
针对多波束条幅存在的残余声线折射影响,加拿大Caris HIPS多波束资料处理软件除了支持声速剖面改正外,还提供了一个折射改正工具。该折射改正工具简单易用,效果所见即所得,能够快速消除声线折射产生的假地形。通过实测数据对这两种改正方法的结果进行了比较。
In order to solve the residual artifacts in the swath affected by sound refraction, there are two of tools in the Cads HIPS multibeam data processing software of Canada, one is traditional SVP correction tool, another is refraction correction tool. The refraction correction tool is very easy to use, and the correction effect is WYSWYG, which can eliminate the artifacts caused by sound refraction rapidly. The purpose of this article is to make a comparison of the effect of using the tools with actual multibeam dataset.
