Low-grazing backscattering efficiency from clustering vegetation

A low-grazing scattering model for vegetation where leaves occur in clusters is developed in this paper. Taken into account of the coherent effects from different clustering scatters. Monte-Carlo method is applied to simulate the low-grazing backscattering from the clustering vegetation that which is distributed randomly or regularly respectively. The results are good used to explain the backscattering enhancement and the grazing incidence characteristic of the clustering vegetation.
