Analysis on the sensing model of suspended sediment concentrations
悬浮泥沙浓度遥感反演模型研究

The characteristics of reflected spectrum of suspended sediments in laboratory with a given size are analyzed,optimal wavelengths of spectrum reflectance are selected and the quantitative sensing model for reflectivity and SSC is established.Including the field measured reflectance and the median diameter(D50)of sediments,a quantitative remote sensing model for the prediction of SSC is established.The result suggests that the principle component model shows the best precision and the power model is much better than the linear model.
