摘要
在分析卫星遥感水深理论模式基础上,结合长江口水域的水沙特性建立了遥感长江口水深的分段模式,给出了相应的数字图像处理方法,所得到的遥感水深图与实测水深图较为一致.
Based on the analyses of the theoretical models of the fathoming method by using satellite remote sensing, a subdivision model for remote sensing of water depth in the Yangtze River estuary is established considering the characteristics of water and sediment. And the corresponding process of the digital image is also presented. The remote sensing bathymetric chart agrees well with the measured one.
