摘　　要：在分析单站合成孔径雷达去取向参数的基础上,研究了双站合成孔径雷达的非对称散射矩阵,利用矩阵代数知识得到双站去取向参数。推导了目标的去取向变换矩阵,将目标散射矢量进行矢量变换,使得研究目标具有相同的取向,目标本身的信息得以凸显。经过去取向变换,对双站模拟图像的特征参数进行分析,为进一步解读双站图像提供了初步手段。The nonsymmetrical scattering matrices of bistatic Synthetic Aperture Radar（SAR） are studied on the basis of the analysis of the monostatic SAR deorientation parameters, and the bistatic deorientation parameters are obtained by using matrix algebra. Deorientation transformation matrix is deduced and the transformation of the target scattering vector is introduced to reduce the influence of randomly fluctuating orientation and make the targets＇ generic characteristics prominent. The targets＇ generic characteristics of the simulated bistatic SAR images are analyzed through the transformation in order to provide a rudimentary method for bistatic SAR images.
