Translational variant bistatic SAR signal space-time feature and processing method

In this paper, we discuss the translational-variant feature of translational-variant bistatic SAR configuration using the space Taylor´s expansion in section II. In section III, a new translational-variant bistatic SAR imaging method is proposed, which uses scaled IFFT technique to eliminate the translational- variant feature of SAR space resolution. Finally, some numerical experiments are conducted to demonstrate the feasibility of this method and discuss the depth-of-focus of the scaled IFFT bistatic SAR imaging algorithms.
