Evaluation of a geometrical autofocus algorithm within the framework of Fast Factorized Back-Projection
Paper i proceeding, 2012

This paper introduces a new autofocus algorithm, specifically suitable for UWB SAR systems. The strategy is integrated in FFBP and relies on varying track parameters stage by stage to obtain a sharp image. Focus measures are provided by an object function (intensity correlation). The algorithm has been tried out successfully on a synthetic data set.
