Paper Abstract

The phase gradient autofocus (PGA) technique is used for automatic estimation and correction of phase errors in spotlight mode synthetic aperture radar (SAR) imagery. This paper presents an overview of the PGA algorithm in iterative and non-iterative versions and shows the results of implementation of this method in C language for real-time applications.
