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.

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.

A Closed-Form Localization Algorithm and GDOP Analysis for Multiple TDOAs and Single TOA Based Hybrid Positioning

Applied Sciences, 2019
Cellular communication systems support mobile phones positioning function for Enhanced-911 (E-911) location requirements, but the positioning accuracy is poor. The fifth-generation (5G) cellular communication system can use indoor distribution systems to

Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization

IEEE Open Journal of Signal Processing
Source localization with time-of-arrival (TOA), time-difference-of-arrival (TDOA), time-delay (TD), received-signal-strength (RSS), or angle-of-arrival (AOA) measurements from several spatially distributed sensors is commonly used in practice.
