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

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.

An anti‐jamming method in multistatic radar system based on convolutional neural network

IET Signal Processing, 2022
For the existing jamming discrimination methods on the multistatic radar system, the single feature of target echo space correlation is utilised as the metric, which leads to the lack of comprehensive feature extraction and universal discrimination ...

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.

Power and Waveform Resource Allocation Method of LPI Netted Radar for Target Search and Tracking

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
A new scenario is considered for the low probability of intercept (LPI) netted radar in simultaneous target search and tracking, and a joint power and waveform resource allocation algorithm is proposed through the optimization of the multi‐dimensional resources.

A Networked Radar Beam Allocation Method for Multi‐Target Tracking in Multi‐Jammer Scenario

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper focuses on the problem of mainlobe interference suppression in radar networks tracking multi‐target scenarios with multiple jammers. A beam allocation method is proposed based on stepwise suppression of mainlobe and sidelobe interference since the beam allocation method has a significant impact on interference suppression performance ...

Distributed Shipborne HFHSSWR Localisation Method Based on Gaussian Markov Fields

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
This paper investigates a distributed shipborne high‐frequency hybrid surface‐surface wave radar (HFHSSWR) model that combines shared sky wave paths with distinct shipboard surface wave paths. This model improves target localisation accuracy and overcoming the limited aperture of single shipboard array.

Multistatic Modular Real‐Time MIMO‐SONAR Systems

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Multistatic SONAR networks (MSNs) improve underwater imaging quality due to increased degrees of freedom. Techniques for bistatic processing, elliptical interpolation and data merging are described, and a real‐time modular SONAR imaging system equipped with these algorithms is tested. Simulations and real‐world measurements demonstrate the capabilities
