Numerical analysis of scattered power from a layer of random medium containing many particles of high dielectric constant - Application to the detection of a water content of soil - Abstract

This paper shows the scattering cross sections of a random medium which is a simple model of moist soil by analyzing a dense medium radiative transfer equation (DMRT). The parameters in the DMRT, the extinction rate and the s cattering coefficient, are calculated by a multiple scattering method calle d our method in this paper. Our method is valid for particles with high die lectric constant like water drops. Characteristics of the scattering cross section are made clear by changing the fractional volume of water and the i ncident angle, polarization of incident waves. We discuss the possibility o f detection of a water content in this approach by using the characteristic s of the scattering cross section.
