Sparsity-aware TDOA localization of multiple sources
, 2013 The problem of source localization from time-difference-of-arrival (TDOA) measurements is in general a non-convex and complex problem due to its hyperbolic nature. This problem becomes even more complicated for the case of multi-source localization where

A Hybrid AOA and TDOA-Based Localization Method Using Only Two Stations
International Journal of Antennas and Propagation, 2021 Target localization plays an important role in the application of radar, sonar, and wireless sensor networks. In order to improve the localization performance using only two stations, a hybrid localization method based on angle of arrival (AOA) and time ...

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.

Optimal Sensor Deployment and Velocity Configuration With Hybrid TDOA and FDOA Measurements
IEEE Access, 2019 Source localization based on the hybrid time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA) measurements from distributed sensors is an essential problem in wireless sensor networks (WSNs).

IET Signal Processing, Volume 2026, Issue 1, 2026.To address the issue that the traditional direct position determination (DPD) method for coprime arrays (CAs) has limited performance in scenarios with low signal‐to‐noise ratio (SNR) and small quantity of observation data, a progressive optimization method based on the averaging of redundant data from virtual array elements is proposed. This method is

Compressive TDOA Estimation Method Based on Amplitude Phase Clustering in Time‐Frequency Domain
IET Signal Processing, Volume 2026, Issue 1, 2026.In the field of signal processing, modulation signals, including phase shift keying (PSK) and quadrature amplitude modulation (QAM), can significantly enhance the signal‐to‐noise ratio (SNR) through aliasing transmission following clustering and sorting.

Reducing Bias for Closed‐Form TDOA Localization in Unified Near‐Field and Far‐Field Model
IET Signal Processing, Volume 2026, Issue 1, 2026.Bias is a fundamental metric for evaluating the average error of an estimator, where lower bias indicates an estimator closer to the true value. Recent studies on time difference of arrival (TDOA) localization have introduced the modified polar representation (MPR) to unify near‐field and far‐field scenarios, enhancing robustness to the source range ...
