Autofocus approach for sparse aperture inverse synthetic aperture radar imaging

open access: yesElectronics Letters, 2015
In the inverse synthetic aperture radar imaging, the autofocus is a required step for generating high‐quality images. However, due to many factors, the aperture data may be sparse so that the classical motion compensation approaches and imaging algorithms are not proper. On the basis of the compressed sensing technique and two optimisation methods (the

Mapping Ice Stream Sensitivity in the Amundsen Sector to Uncertainty in Ice Velocity Observations

open access: yesGeophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Satellite‐derived ice‐velocity products are essential for initializing ice‐sheet models and forecasting ice evolution in a warming climate. Understanding where sea‐level rise (SLR) projections are sensitive to observational errors is key to improve model accuracy and reduce uncertainty.

Toward an optimal inversion method for synthetic aperture radar wind retrieval [PDF]

open access: yesJournal of Geophysical Research: Oceans, 2002
In recent years, particular efforts have been made to derive wind fields over the oceans from synthetic aperture radar (SAR) images. In contrast with the scatterometer, the SAR has a higher spatial resolution and therefore has the potential to provide higher resolution wind information.

Maximum entropy regularization in inverse synthetic aperture radar imagery [PDF]

open access: yesIEEE Transactions on Signal Processing, 1992
The method of maximum entropy is applied to the regularization of inverse synthetic aperture radar (ISAR) image reconstructions. This is accomplished by considering an ensemble of images with associated 'allowed' probability density functions. Instead of directly considering the 'solution' to be an image, the author takes it to be the a posteriori ...
