本文提出利用蒙特卡罗算法研究植被散射及其低掠角散射特性.根据双层植被的散射模型,考虑到植被层内各散射体场的相干和多径效应,利用蒙特卡罗算法模拟随机分布和簇规则分布植被的低掠角散射系数,适当解释植被散射的后向增强和掠射特性.

The Monte Carlo method is applied to study the vegetation scattering and its low-grazing characteristic.Based on the two-layer model,taking into account of the coherent and multipath effects from different scatterers,Monte-Carlo method is applied to simulate the low-grazing scattering coefficient from the vegetation which is distributed randomly or clustered respectively.The results are appropriately used to explain the backscattering enhancement and the low-grazing scattering of the vegetation.
