| 摘 要： | 利用Fournier and Forand(FF)体散射函数近似计算方法模拟太湖水体的体散射函数以及散射相函数,进而分析太湖水体体散射函数和散射相函数的特性,以及与波段、深度之间的变化关系,空间分布差异。研究表明,太湖水体体散射函数表现为具有极强前向散射特性的大颗粒物散射特征,体散射函数随波段变化的差异性主要体现在后向方向上,散射相函数的变化规律与体散射函数较为相似;而随着深度的变化体散射函数几乎没有变化,但散射相函数表现出了较为明显的层状特征;体散射函数和散射相函数在空间上表现出了较大的差异性,这种差异性随着散射角的增大而不断地加强。

| Abstract: | The approximate calculation method of Fournier and Forand (FF) volume scattering function was used to simulate the volume scattering function and scattering phase function in Lake Taihu. The properties, temporal and spatial variation of volume scattering function and scattering phase function were analyzed. The research indicated that the volume scattering function in Taihu Lake belonged to the big size particle, which had strong forward scattering property. The variations of volume scattering function for the wavelength were mainly in backward. The scattering phase function was similar with the volume scattering function. There was almost no change of volume scattering function with increasing of depth, but the scattering phase function showed significant stratified property. The spatial variations of volume scattering function and scattering phase function weresignificant, which will become more obvious with the increase of scattering angle. |
