A new method for solving the RTE of multilayer medium containing scattering layers

In the remote sensing of the sea surface (temperature, wind speed, wind direction, the height of wave, etc.) by both active and passive remote sensing instruments (SAR, scattermeter, altimeter, radiometer, etc.), the atmosphere (including cloud and rain) has a large influence especially for instruments working at millimeter and submillimeter wavelengths. Solution methods are considered for the radiative transfer equation for a multilayer medium containing scattering layers; for example the invariant imbedding method. The huge amount of calculations and the little flexibility of computer program make this method impracticable. The authors propose a new method for the solution of the RTE of a multilayer medium containing scattering layers such as cloud and rain
