Distributed spaceborne SAR and medium-or high-orbit SAR are receiving increasing focus with the development of satellite technology, while the extended synthetic aperture length and long baseline pose new challenges to the bistatic SAR imaging. In this work we propose a new hyperbolic equivalence method based on Bakhshali approximation. Besides, an appropriate CS imaging procedure is designed. Compared to the original method, the proposed method meets the requirements. Finally, the simulation results verify the validity of the proposed method.
