Polarimetric radar discrete scatter model of vegetation

A microwave bistatic scatter model which predicts the scattering matrix (or Mueller matrix) is developed by using the discrete modelling technique for the vegetation. Vegetation is modelled as a random collection of scatterers. Leaves are modelled by a circular disc and branches are modelled by a circular cylinder. The modelling procedure assumes that the fractional volume of the plant material is small. The matrix of the polarimetric bistatic scattering coefficients is derived by employing the distorted Born approximation and the result is valid for the P-, L-, and C- band SAR frequencies
