摘要：

Despite the tremendous progress in synthetic aperture radar (SAR) navigation systems, complete elimination of phase errors caused by random platform is challenging Automatic phase correction algorithms have been introduced for trial overcome this, with the PGA algorithm being the most extensive and. However, PGA exhibits shortcomings, especially its repetitive nature, which leads to increased computation time and uncertainty in obtaining optimal results with a fixed number of iterations. This paper presents a new automatic algorithm designed to overcome the efforts of previous methods and correct PGA-related phase errors without the need for repeated iteration The proposed algorithm exhibits improved performance in terms of phase error compensation cost, especially compared to existing methods.
