Abstract
In this paper, the categories of phase errors in UWB-SAR (Ultra-Wideband Synthetic Aperture Radar) are identified at first. Following that, the relationship between phase error magnitude and the level of image degradation is quantified in simplicity. At last, some autofocus techniques are described to reduce space-variant phase errors
