Joint sparsity-driven inversion and model error correction for radar imaging [PDF]
, 2009 Solution of inverse problems in imaging requires the use of a mathematical model of the observation process. However such models often involve errors and uncertainties themselves. The application of interest in this paper is synthetic aperture radar (SAR)

Measurement of Englacial Velocity Fields With Interferometric Radio Echo Sounders
Journal of Geophysical Research: Earth Surface, Volume 130, Issue 6, June 2025.Abstract The surface velocity of ice sheets is now measured at high spatial and temporal resolutions by satellite‐borne platforms. The availability of this data has enabled rapid progress in both monitoring the evolution of ice sheets and understanding their underlying physical processes.

Differentiable Rendering for Synthetic Aperture Radar Imagery [PDF]
arXiv, 2022 There is rising interest in differentiable rendering, which allows explicitly modeling geometric priors and constraints in optimization pipelines using first-order methods such as backpropagation. Incorporating such domain knowledge can lead to deep neural networks that are trained more robustly and with limited data, as well as the capability to solve

Analysis of the Utilization of Machine Learning to Map Flood Susceptibility
Journal of Flood Risk Management, Volume 18, Issue 2, June 2025.ABSTRACT This article provides an analysis of the utilization of Machine Learning (ML) models in Flood Susceptibility Mapping (FSM), based on selected publications from the past decade (2013–2023). Recognizing the challenge that some stages of ML modeling inherently rely on experience or trial‐and‐error approaches, this work aims at establishing a ...

An improved inverse synthetic aperture radar range alignment method based on maximum contrast
Jurnal Engineering, 2019 Inverse synthetic aperture radar (ISAR) is an important tool for non-cooperative ship imaging, and one key step of ISAR imaging is range alignment. To achieve the range alignment with high precision, efficiency and robustness, an improved ISAR range ...
