The application of airborne synthetic aperture radar (SAR) ship target imaging technology is of great significance in the realm of marine surveillance. Unlike stationary target SAR imaging, the moving ship targets are shifted and defocused in the SAR image because of their motions. Therefore, it is necessary to obtain the echoes of each moving ship target for following imaging to get an accurate SAR imaging result. This paper proposes a novel echo separation method for moving ship targets. The entire scene is imaged firstly. Then, the SAR imaging result is used to extract the sub-image containing the region of interest (ROI) of the moving ship target. Lastly, the moving ship target echoes are obtained by inverse imaging of the extracted sub-image. The proposed method is validated by the results obtained from simulation experiments.
