A radar coherent scattering model for forest canopies based on fractal-generated trees and forest dynamics models is established. In order to obtain the position of scatterers, the fidelity of forest structure is simulated by two models: forest dynamics and fractal-generated trees model. Forest dynamics model, ZELIG, can get stand structural composition in some ages. A fractal-generated trees model, L-system, can simulate a 3D tree. Every scatterers are obtained by linking up ZELIG with L-system. Radar coherent scattering model simulates the information of radar backscattering by output of ZELIG and L-system. The prediction results of coherent model is validated by the JERS-1 SAR and Envisat ASAR data from the pure birch of Changqing test site in Daxing';anling.
