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.

International Journal of Antennas and Propagation, 2019 In this paper, an estimation algorithm for the position and velocity of a moving target in a multistatic radar system is investigated. Estimation accuracy is improved by using bistatic range (BR), time-difference-of-arrival (TDOA), and Doppler shifts ...

IET 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
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.
