针对多波束测深系统测量的特点,分别分析声速改正技术和潮位改正技术.从声速在海水中的传播出发,阐述海水中声速的测量,对声速的较正方法进行探讨,随后针对潮汐效应的影响,对多波束测深数据进行潮位改正,并利用海上试验实测的多波束测深数据,将处理后的数据绘制成海底地形数字地图.
針對多波束測深繫統測量的特點,分彆分析聲速改正技術和潮位改正技術.從聲速在海水中的傳播齣髮,闡述海水中聲速的測量,對聲速的較正方法進行探討,隨後針對潮汐效應的影響,對多波束測深數據進行潮位改正,併利用海上試驗實測的多波束測深數據,將處理後的數據繪製成海底地形數字地圖.

Based on the characteristic of the Multi-beam bathymetric system,the sound velocity correction technique and the tide correction are analyzed.On the basis of the sound velocity spreaded,the measure of sound velocity is expatiated and the means of the sound correction is discussed.Furthermore,the analyzing for the tide correction is discussed with the influence of the tide.On the basis of the data of the multi-beam bathymetric system which are measured in the test sea area,the sampling depth data which had been processed are developed to form the depth overlay map,isoline map and stereogram,and so the digital map is made.
