DOI: 10.1109/jstars.2016.2602378

Abstract: In this paper, we propose a new and efficient inverse synthetic aperture radar (ISAR) autofocus technique by introducing eigenimages to boost the speed of the traditional autofocus algorithms. First, a preprocessing step is applied to… read more here.

Published in 2020 at "IEEE Transactions on Image Processing"

DOI: 10.1109/tip.2020.2988143

Abstract: Existing two-dimensional (2D) autofocus algorithms, exploiting the known structure of 2D phase error, lack the error estimation accuracy in the case of a low signal-to-noise ratio (SNR) due to the non-exhaustive use of the echo… read more here.
