Multiview Three-Dimensional Interferometric Inverse Synthetic Aperture Radar
IEEE Transactions on Aerospace and Electronic Systems, 2019 Three-dimensional (3D) inverse synthetic aperture radar (ISAR) imaging has been proven feasible by combining traditional ISAR imaging and interferometry. Such technique, namely Inteferometric ISAR (InISAR), allows for the main target scattering centers to be mapped into a 3-D spatial domain, therefore forming 3-D images under the form of 3-D point ...

A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Refocusing Moving Ship Targets in SAR Images Based on Fast Minimum Entropy Phase Compensation
Sensors, 2019 Moving ship targets appear blurred and defocused in synthetic aperture radar (SAR) images due to the translation motion during the coherent processing. Motion compensation is required for refocusing moving ship targets in SAR scenes.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract A persistent challenge in hydrological modeling is reliably transferring predictive skill across time and among basins that appear distinct based on conventional static attributes. Here we address this challenge by leveraging Google's newly released data set generated from the AlphaEarth Foundations model, providing 64‐dimensional satellite ...

Multibeam single frequency synthetic aperture radar processor for imaging separate range swaths [PDF]
, 1982 A single-frequency multibeam synthetic aperture radar for large swath imaging is disclosed. Each beam illuminates a separate ""footprint'' (i.e., range and azimuth interval).

Multiple feature-enhanced SAR imaging using sparsity in combined dictionaries [PDF]
, 2012 Nonquadratic regularization-based image formation is a recently proposed framework for feature-enhanced radar imaging. Specific image formation techniques in this framework have so far focused on enhancing one type of feature, such as strong point ...
