The influence of high‐frequency platform vibration needs to be considered in the synthetic aperture radar (SAR) signal processing, especially at the case that the carrier frequency is in high frequency band. The existence of the vibration will cause the SAR images not to focus. In this study, a novel method for SAR imaging is proposed to enhance the focus performance, where the inverse radon transform based method is employed to estimate the vibration parameters. The effectiveness of the proposed method is verified by simulation results.
