【摘要】 依据L-系统分形的思想生成由树枝和树干组成的分形树模型,在此基础上采用随机分布两种不同形状的树叶模型以构建整棵树。然后采用映射投影算法(MPA)计算树的体散射、消光和二次散射,根据SAR成像的几何关系,投影叠加得到SAR图像。更多还原

【Abstract】 In this paper, a fractal tree model consisted of stems and truck based on L-System is introduced. Randomly distributed forest of fractal trees are generated for SAR imaging simulation. Then, the Mapping and Projection Algorithm(MPA) is used to compute the volume scattering, extinction and volume-ground scattering. Finally, simulated SAR image is formed via scattering accumulation according to imaging geometry.更多还原
