A method for localization TDOA estimation based on signal‐level fusion and analysis

Electronics Letters
Passive localization using time difference of arrival (TDOA) is one of the common methods for radiated source target localization, and its localization performance depends on the accuracy of TDOA estimation. In many localization scenarios, the signals of

A Tightly Coupled Fusion Positioning Method Based on Particle Filtering With Effective Particle Neighbourhood Attraction Optimisation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the limitations of existing wireless and inertial navigation systems, this paper proposes a high‐precision integrated positioning scheme based on particle filtering. The method introduces a high‐weight particle neighbourhood attraction mechanism to solve the common issue of particle degeneracy.

High‐Precision Localisation of Coherent Emitters via Iterative SDF‐DPD on Mobile Platforms

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes an iterative direct localisation algorithm. This algorithm does not require subarray‐based spatial smoothing and works in both partially and fully coherent signal environments. ABSTRACT The proliferation of illegal radiation sources significantly threatens reliable communication and stable operation of industrial facilities.

Lightning Location and Mapping System Using Time Difference of Arrival (TDoA) Technique

, 2011
Lightning strike is a dangerous natural phenomenon that can cause various problems. Telecommunication subscriber lines (TSLs) and electrical power lines are two systems that are almost always affected by nearby lightning strikes. Voltages in the telecommunication subscriber line (TSL) do get induced by nearby lightning strikes.

Recursive Radar Signal Deinterleaving by Semantic Segmentation Using Recurrent Neural Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
We propose two recursive methods for radar signal deinterleaving. They are based on neural networks, and one includes a cognitive approach aiming to reproduce the behaviour of a human operator. Both are trained and evaluated on real‐world data and augmented data. ABSTRACT We propose two methods for radar signal deinterleaving.

Non‐Coherent Synthetic Aperture Passive Source Localisation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper addresses the problem of determining, from passive measurements on moving receivers, the position of an unknown source of electromagnetic (or acoustic) waves. This source is assumed to lie on a known surface, and the wave propagation environment is assumed to be free space. This paper addresses the problem in which there are uncertainties in
