Target detection, ISAR imaging and tracking capabilities of a passive radar net utilising barrage jamming signals

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2144-2154, November 2024.
This paper demonstrates the possibility of utilising a ground‐based barrage jammer as an illumination source for passive radar detection, tracking and ISAR imaging. This article will present some of the outcomes of field trials conducted within the international electronic warfare exercises.

Joint sparsity-driven inversion and model error correction for radar imaging [PDF]

open access: yes, 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)

Broadband multi‐carrier linear frequency modulation signal reception with subcarrier frequency offset deramp processing

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2325-2332, November 2024.
The authors propose a multi‐carrier LFM signal reception method based on subcarrier frequency offset deramp processing. By properly introducing a carrier frequency interval difference between the transmit and reference signals, multi‐carrier LFM signal deramp processing is implemented through frequency mixing, which allows crosstalk‐free separation of ...

Target Oriented High Resolution SAR Image Formation via Semantic Information Guided Regularizations

open access: yes, 2017
Sparsity-regularized synthetic aperture radar (SAR) imaging framework has shown its remarkable performance to generate a feature enhanced high resolution image, in which a sparsity-inducing regularizer is involved by exploiting the sparsity priors of ...

Measurements and analysis of the radar cross section of chaff dipoles

open access: yesIET Radar, Sonar &Navigation, Volume 18, Issue 11, Page 2182-2188, November 2024.
Photo of a filament under test in a stereo‐foam support. Abstract A free space test method to measure the Radar Cross Section (RCS) of single dipole elements is presented. The method is such that dipoles can be measured over a large range of frequencies, in free space and without the need of an anechoic chamber.

An improved inverse synthetic aperture radar range alignment method based on maximum contrast

open access: yesJurnal 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 ...
