摘要
讨论了目标的双站散射矩阵,给出了散射矩阵的各种表达形式以及它们之间的转换关系,指出了Sinclair双站散射矩阵的特点,提出了求解散射矩阵特征根的途径.以2λ×2λ平板的镜面散射为例,利用散射矩阵的特征根,求解了最优发射极化与最大散射功率之间的关系。
This paper discusses the bistatic scattering matrix and gives the various expressions of the bistaticseattering matrix in different Cartesian coordinates as well as the transform of different expressions. The characteristicsof Sinclair bistatic scattering matrix are described. The way to solve the eigenvalues of the scattering mateix is presented .As an application illustration of this study,we use the eigenvalues of the scattering matrix of a 2λ×2λ plare to find out the relations between the optimal seattered power and optimal transmitting polarization for specular scattering.
