摘要

This paper presents the moving target focusing method, which allows focusing moving targets in complex synthetic aperture radar (SAR) images without raw data. The method is developed on the range migration algorithm, where focusing moving target is an interpolation step in the wave domain. The simulated results are provided in the paper to illustrate the proposed method whereas the experimental results show its practicality. The method can be flexibly applied from small area to the whole SAR scene.
