N2 - The missile's flight trajectory in the final guidance section is complex and generally has a high diving velocity. Therefore, the missile-borne SAR is faced with the problems of high maneuverability, high squint mode, and curved trajectory, conventional SAR imaging algorithms are no longer applicable. In this paper, a modified CSA suitable for wide scenes is proposed. Firstly, using the method of series reversion derive the two-dimensional spectrum, and then analyzing the range bending factor under wide scene condition which determine the scaling equation with curve trajectory. Based on this, a modified CSA algorithm can be derived. The simulation results show that this algorithm can achieve high-precision imaging under the condition of diving maneuver.
