A sparsity-driven approach for joint SAR imaging and phase error correction [PDF]

open access: yes, 2012
Image formation algorithms in a variety of applications have explicit or implicit dependence on a mathematical model of the observation process. Inaccuracies in the observation model may cause various degradations and artifacts in the reconstructed ...

Inverse Synthetic Aperture Radar Imaging: A Historical Perspective and State-of-the-Art Survey

open access: yesIEEE Access, 2021
Radar can obtain high spatial resolution at large operating distances, and its operation is largely independent from weather and lighting conditions. This makes it an important instrument in an ever-increasing number of applications requiring robust and ...

A nonquadratic regularization-based technique for joint SAR imaging and model error correction [PDF]

open access: yes, 2008
Regularization based image reconstruction algorithms have successfully been applied to the synthetic aperture radar (SAR) imaging problem. Such algorithms assume that the mathematical model of the imaging system is perfectly known.

Parametric Sparse Representation and Its Applications to Radar Sensing

open access: yesLeida xuebao, 2016
Sparse signal processing has been utilized to the area of radar sensing. Due to the presence of unknown factors such as the motion of the targets of interest and the error of the radar trajectory, a predesigned dictionary cannot provide the optimally ...

Translational Motion Compensation for ISAR Imaging Based on Range Joint Fast Orthogonal Matching Pursuit Algorithm

open access: yesIEEE Access, 2022
Accurate translational motion compensation (TMC) is the key procedure of inverse synthetic aperture radar (ISAR) imaging. Under the condition of sparse aperture, the correlation of adjacent pulses is severely destroyed, which brings a few challenges to ...
