Moving Target Imaging Using GNSS-Based Passive Bistatic Synthetic Aperture Radar

open access: yesRemote Sensing, 2020
Current studies of global navigation satellite systems (GNSS)-based bistatic synthetic aperture radar (GNSS-SAR) is focused on static objects on land. However, moving target imaging is also very significant for modern SAR systems. Imaging a moving target

FrFT-Based Scene Classification of Phase-Gradient InSAR Images and Effective Baseline Dependence [PDF]

open access: yes, 2015
In the literature, scene recognition from interferometric synthetic aperture radar (InSAR) images has been mainly focused on the joint use of the backscatter intensity and the coherence between interferometric image pairs.

Vehicle Target Detection Based on Cross‐Modality Projective‐Invariant Features Extracted from Unpaired SAR and Infrared Images

open access: yesElectronics Letters, Volume 61, Issue 1, January/December 2025.
A novel dual‐channel context‐guided feature‐alignment network (CGFAN) that is capable of fusing the cross‐modality projective‐invariant features extracted from unpaired SAR and IR images is proposed. First, region of interest matching between SAR and IR images are realized based on special landmarks exhibiting consistent cross‐modality features.

Modelling real‐world effects in near‐field SAR collections for compressive sensing

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.

Characterisation of Resident Space Objects and Synchronisation Error Compensation in Multistatic Interferometric Inverse Synthetic Aperture Radar Imaging

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This article presents a study on interferometric inverse synthetic aperture radar (ISAR) for three‐dimensional imaging and rotational velocity estimation. The study focuses on synchronisation error compensation in a multistatic setup with three ground‐based radars and non‐orthogonal baselines.

Polarimetry for Sparse Multistatic 3D SAR

open access: yesIET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
3D SAR imagery provides target height information and removes layover artefacts, but it has impractical sampling requirements. This article develops the PolSSARVI approach, where a sparsely formed set of polarisation‐weighted interferograms are combined for determining the 3D coordinates of scatterers.
