#### Abstract

Remote sensing has been widely used as an earth observation technique to study the polar region. Volume scattering process is one of the scattering processes that occur in a layer of discrete random scatterers in remote sensing. In certain layer, volume scattering is significant and important to determine the value of backscattering coefficient. Previous study modelled the volume scattering only for first and second order. In this paper, a third order volume backscattering coefficient formulation is derived and added into the theoretical modelling of volume scattering, and its backscattering coefficient is analysed for different types of layer configuration embedded with discrete random scatterers. The condition of which the third order volume scattering may be important is studied. Results show that, third order volume scattering activity is significant when the scatterers in the layer are larger and with higher permittivity in both lower and higher incident angles, for all the frequency range studied.
