1967年,Geary利用彩色透明片绘制了水的深度图。1969年,Polycn应用光的折射和颜色变化,测定了密执安(Michigan)湖几个剖面的水深,但受到边缘效应的影响。1970年,Polycn利用水的不同波长的选择透射性质,建立了方程,给出了水深与多光谱扫瞄仪两通道输出的关系(至少两通道)。1974年,渡道贯太郎建立了水深、水的衰减系数与海底反射率之间的函数关系。本文从海水的透射率、后向散射系数、海底反射率
In 1967, Geary plotted the water’s depth map with colored transparency. In 1969, Polycn applied light refraction and color changes to determine the depth of several sections of the Lake Michigan, but was influenced by the effects of the edge. In 1970, Polycn used the selective transmission properties of different wavelengths of water to establish the equation and gave the relationship between the depth of water and the two-channel output of the multispectral scanner (at least two channels). In 1974, Koji Watanabe established a water depth, the water attenuation coefficient and seafloor reflectivity as a function of. In this paper, the transmissivity, backscatter coefficient and seafloor reflectivity of seawater are presented
