Numerical simulation in remote-sensing reflectance of suspended sediment water

The aim of this paper is to study relation between physical property of suspended sediment and remote-sensing reflectance using numerical simulation. We studied the transport mechanism of light in dense suspended sediment water body by the aid of numerical simulation. The T-Matrix method (TMM) and the Invariant Imbedding Methods was selected as basic methods of numerical simulation. Two formulas was applied in the simulation. The first one described the relation between volume scattering phase function and Stokes matrix. The other one shows the relation between albedo and scattering section. These formulas connect the T-Matrix Method and the Invariant Imbedding Methods and put them work together for simulating the mechanism of light transfer in suspended sediment water body. The results of numerical simulation coincide with in-stitu data. We found the monotone relations between the physical parameters of suspended sediment and the spectrum of remote-sensing reflectance. The monotone relations mean that retrieving physical property from spectrum is feasible.
