Statistical Analysis of Performance of Optimisation‐Based SAR Autofocus
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.Transionospheric SAR autofocus is a variational algorithm designed to overcome the limitations of conventional autofocus methods in correcting ionospheric distortions in spaceborne SAR images. This study provides a systematic statistical analysis of its robustness, examining the effects of turbulence, clutter, and noise on performance.
