Abstract: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.
