摘　　要：为提高浅水多波束测深资料处理成果质量,基于澳门海域浅水多波束测深资料,提出应用POS/MV大地高数据计算实时潮汐数据,探讨了浅水多波束测深资料声速校正方法。结果表明,经过潮汐改正和声速改正后资料处理成果质量明显提高,解决了浅水多波束测深资料处理中的难题,本方法可为浅水多波束测深资料处理提供重要指导。In order to improve the quality of shallow water multibeam echosounding data processing results,based on the shallow water multi-beam data of the Macao sea area,the application of POS/MV geodetic altimetry data to calculate real time tide data is proposed,and the shallow-water multi-beam sound velocity correction method is discussed.The results show that the quality of data processing results is significantly improved after tide correction and sound velocity correction,which solves the problem of shallow water multi-beam sounding data processing.This method can provide important guidance for shallow water multi-beam data processing.
