Abstract：Discrete vegetation scattering model based no distorted Born approximation solution is derived. The backscattering mechanism is illustrated. Scattering amplitude functions and model for calculating permittivity are presented. Comparisons between model predictions and field measurements on radar backscattering coefficients for corn canopy showed a reasonable good agreement at L-band for HH,VV polarizations.
