摘　　要：介绍了造成多波束测深数据失真的因素,如安装误差、声速剖面误差、潮汐加载误差等,分析了这些因素造成多波束测深数据失真的机理,并分别从外业测量和室内后处理两方面提出了解决办法。本文提出的方法可为后续的多波束勘测和相关研究提供指导或参考。This article introduces the factors which cause distortion in multi beam bathymetry data,such as installation errors,sound velocity profile errors,tidal loading errors,etc.It analyzes the mechanisms of these factors causing distortion in multi beam bathymetry data,and proposes solutions from two aspects:field measurement and indoor post-processing.The method proposed in this article can provide guidance or reference for subsequent multi beam surveys and related research.
