Improved subaperture clutter suppression method for SAR moving target imaging

摘要

In this paper, improved subaperture clutter suppression method for synthetic aperture radar (SAR) moving target imaging is proposed. Theoretical basis of subaperture imaging method is given. The position rules of moving target and clutter in subaperture are utilized to separate and reduce clutter effectively while preserve the moving target signal. The suppression process is implemented automatically avoiding operator interaction. Real data experiment verifies the effectiveness of this method.
