Abstract
In this paper, the equations describing the centroid location of target shadow and the terms which cause it to defocus are derived for images formed by spotlight SAR algorithm. Based on the derived equations, a shadow edge sharpening technique is proposed. The proposed technique is tested on real data and results show that it can sharpen and bring out even faintly visible shadow in ultra high resolution SAR images.
