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

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

Polarimetry for Sparse Multistatic 3D SAR
IET 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.
