It is very important to study forest radar backscattering mechanism for forest microwave remote sensing applications. ln this paper

we use the discontinuous canopy microwave backscattering model in conjunction with the ground truth measurements to model the radar backscatter behavior from pine forests at the Zhaoqing area

Guangdong Province. lt is very well for the model to predict the radar backscatter of pine stand at L-

and C-band

and the contribution from each of the scattering mechanisms to the total backscatter is calculated. The results are used to discuss the effect of the physical properties of the forest components on the radar backscatter. They are also used to show not only the backscatter but also the relative contribution from various scattering mechanisms that will help in the quantitative interpretation of SAR data. So the comparison of the backscatter coefficients from the model prediction and SIR-C data is done

and the radar backscatter mechanism of pine forests is analyzed and discussed.
