摘要:
针对内陆湖泊高散射特性水体,利用Hydrolight模拟软件模拟不同散射系数、风速、太阳天顶角条件下水表面以下辐照度比R(0-)与bb/(a+bb)的比值g,利用Gordon线性方程和二次方程对g值进行拟合,分析散射系数、风速、太阳天顶角等因素对拟合方程系数和多次散射项的影响,分析结果表明二次方程系数受太阳天顶角和风速影响的范围明显小于线性方程,并且与线性方程相比二次方程对多次散射作用的表达和实际状况以及前人研究结果更加相符,从而建立高散射特性水体中考虑多次散射作用的水表面以下辐照度比R(0-)与bb/(的改进关系式, 利用新的模拟数据对该表达形式进行检验, 误差范围为- 41 015 8% ~ 41498 1%, 说明该模型能够较好地应用于R ( 0- )的精确计算或利用R ( 0- ) 准确反演固有光学属性, 在湖泊水色遥感方面具有较好的应用前景.
Abstract:
Using the optica l simu lation softw areH ydro light, this paper sim ulates the spec ific va lue g between the irrad-i ance reflectance under w ater sur face and the bb /( a + bb ) w ith d ifferen t scatte ring coe fficien ts, w ind speeds and so lar zenith ang le in h igh sca tter ing w ater body.
