摘要
在系统分析多波束测深数据的误差来源与性质的基础上，介绍了条带式多波束测深仪所采用的误差处理的理论模型。针对海洋测量的特点，特别强调了基于趋势面分析的粗差探测与剔除和相邻条带数据的整体拼接以及对航向误差的改正等关键问题。本文介绍的误差处理模型对保证多波束测深系统必要的精度和数据质量有着重要的实际意义。
As a good choice of more powerful automatic batymetric survey techniques with high accuracy and full coverage,the multibeam strip sounder equipped for the first middle pelagic survey vessel made in China has been brought out recently.Based on systematic analysis to the error sources and error properties of multibeam soundings,the theory models for error processing will be presented in this paper.Especially based on trend surface analysis,the methods for gross error process and strips mosaic,and heading correction will be stressed.
