摘要
本文用散射理论建立和推导出复合随机介质中的一阶矩和二阶矩方程。采用等效格林函数表示介质的随机性对两次散射之间传播的作用。计算了有随区域对波场的散射强度的角分布。并给出在远场近似下,波场的 Stokes 矢量的微分散射矩阵。
The scattering theory in composite random medium has beer established in this paper.The equations satisfied by first moment and second momend of wave field have been derived.Effective Green Function is used to express the action of the random medium to the wave in the process of twice Seatte ring.The angle distribution of scattering intensity by limited region is caleu lated.The scattering matrix for Stokes Vector is given also.
