中文摘要：

基于修正的Born近似解得到离散植被散射模型，说明该模型中的植被散射机理，给出圆柱、椭圆片的散射幅度函数，以及植被、土壤的介电常数模型；在L波段下模型应用于玉米植被，得出HH，VV极化情况下的后向散射系数，同时与AIRSAR实验获得的数据比较，验证了同极化HH情况下模型的准确性。

英文摘要：

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.
