摘要：
In recent years, Orthogonal Frequency Division Multiplexing (OFDM) signal has been widely used in Synthetic Aperture Radar (SAR) imaging research due to its orthogonality and large bandwidth. Compared with the traditional SAR, OFDM SAR has certain advantages in imaging applications because of its unique signal characteristics. Nevertheless, OFDM SAR faces many challenges. In this paper, on the basis of different antenna configurations, the problems and studies of single-antenna OFDM SAR imaging and multi-antenna MIMO OFDM SAR imaging are reviewed. The imaging methods of SAR/MIMO SAR based on OFDM and cyclic prefix OFDM signals are discussed, and some possible future research directions of OFDM SAR are presented. © 2020 Institute of Electronics Chinese Academy of Sciences.
