用自然地表非球形散射体全极化一阶散射的Mueller矩阵解，在选定高空间分辨率条件下，计算具三维空间结构与非均匀分布的植被地表的全极化后向散射。用射线跟踪法，按射程计算将散射投影在平面图像对应单元的像素点上，得到自然地表的雷达图像模拟。改变非均匀地表的组成，如树木数目与高度、下垫地表、隐藏目标等，产生各种条件下自然地表景象产生的雷达图像模拟。作为一个对比，模拟图像与机载SAR图像在散射量级以及P，L，C波段多通道散射的物理解释上作了比较。

Employing the Mueller matrix solution of random non-spherical particles, fully polarimetric scattering from heterogeneous canopy surfaces with 3-dimensional spatial structure is calculated. By using the ray tracing method, the scattering from all cells of scatters under a certain radar resolution is mapped into the image pixels. The radar images are simulated for different spatial structures such as number and density of trees, underlying land media, embedded target, etc. It is also compared with the AirSAR image for data validation and image physics.
