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

IET 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.

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

IET 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 ...

3-D High-Resolution ISAR Imaging for Noncooperative Air Targets

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
This article uses the inverse synthetic aperture radar (ISAR) imaging method to present real-world tests on 3-D radar imaging of noncooperative air targets. Initially, the fundamentals of 3-D ISAR are introduced.

Research of InISAR imaging based on joint translational compensation

The Journal of Engineering, 2019
In order to solve the problem that conventional inverse synthetic aperture radar three-dimensional (InISAR 3D) imaging methods need too much computation and so many restrictions in image registration step, this study proposes an InISAR 3D imaging ...

Measurements and analysis of the radar cross section of chaff dipoles

IET 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.

Three‐dimensional interferometric inverse synthetic aperture radar imaging of ship target based on cubic phase signal model

IET Radar, Sonar &Navigation, Volume 18, Issue 10, Page 1691-1709, October 2024.
This paper proposes a three‐dimensional interferometric inverse synthetic aperture radar imaging algorithm for the ship targets based on the cubic phase signal (CPS) model. This method approximates the azimuth echo signal as a CPS and utilises the particle swarm optimisation algorithm to estimate the higher order phase coefficients.

SDRnet: A Deep Fusion Network for ISAR Ship Target Recognition Based on Feature Separation and Weighted Decision

Remote Sensing
Existing methods for inverse synthetic aperture radar (ISAR) target recognition typically rely on a single high-resolution radar signal type, such as ISAR images or high-resolution range profiles (HRRPs).
