摘要
通过分析波束形成的原理与实测数据处理得出结论:表层声速误差将对多波束测量产生不可挽回的错误;而当表层声速正确、声速剖面误差时,在后处理可以通过适当的声速剖面加以改正。
The paper comes to the conclusion through analysis of the principles of beamforming and the measured data processing, ff there are some errors in measured surface sound velocity, it will have an irreparable error for the multibeam data;while the surface sound velocity is right, and sound velocity profile has error, the surveyed data can be recorrected by the appropriate sound velocity profile in post-processing.
