Based on the collected high precision multibeam sonar data from hydrothermal active area of Juan de Fuca Ridge,the northern section of the East Pacific Rise,we used the weighted moving average algorithm to generate the high-precision seabed DTM and we obtained high-resolution seabed sonar mosaic image by use of image processing technology.And we further processed and analyzed the seabed topography and submarine sonar image characteristics.Through sonar data processing and analysis,we had a preliminary understanding of seabed topographic features of hydrothermal area of the Juan de Fuca Ridge which are certain reference for China's oceanic survey and hydrothermal area investigation.%基于收集到的东太平洋海隆北段Juan de Fuca Ridge热液活动区的高精度多波束声纳数据,应用加权移动平均算法,生成典型的高精度海底DTM;应用声纳图像处理技术,生成高分辨率海底声纳镶嵌图,并对其海底地形及海底声学图像进行处理和分析.通过处理与分析,对JFR热液区海底地形地貌特征有了初步认识,对于我国大洋调查和海底热液区探测具有一定的借鉴作用.
