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

Constrained Weighted Least-Squares Algorithms for 3-D AOA-Based Hybrid Localization
IEEE Open Journal of Signal ProcessingSource 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.
