An Iterative Method for Moving Target Localization Using TDOA and FDOA Measurements

IEEE Access, 2018
For moving targets localization, incorporating frequency-difference-of-arrival (FDOA) measurements in the commonly used time-difference-of-arrival (TDOA) positioning systems will improve performance.

Robust Source Localization Using TDOA and FDOA with Receiver Location Errors

Leida xuebao, 2020
To address the low location accuracy and poor robustness of existing methods, error correction to improve the Stage 2 of the original Two-Stage Weighted Least Squares (TSWLS)-based methods is proposed, which involves a robust moving source localization ...

Predicting and Clustering Attitude‐Induced Divergence in Cross‐Array AOA Measurements for LEO Satellites

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Example of cluster identification of attitude configurations to avoid in the attitude space (in terms of angles of roll, pitch and yaw) for a payload composed by a cross antenna array with angle of arrival technology for CubeSats platforms. ABSTRACT Satellite geolocation of radio‐frequency emitters increasingly relies on compact angle‐of‐arrival (AOA ...

A Hybrid Distance Estimation for Wireless Body Sensor Networks

International Journal of Distributed Sensor Networks, 2013
Wireless body area networks become a new research issue in recent years. In this paper, we propose hibernation and distance estimation schemes for wireless USB (WUSB) over wireless body area networks (WBAN) hierarchical protocol for body sensor networks (

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

A Novel Estimator for TDOA and FDOA Positioning of Multiple Disjoint Sources in the Presence of Calibration Emitters

IEEE Access, 2020
Multiple-target localization is extensively applied in wireless connected networks. However, sensor location uncertainty is known to degrade significantly the target localization accuracy.

A Direct Localization Method for Coprime Arrays Based on Averaging of Redundant Data of Virtual Array Elements

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

Barriers and Facilitators of Home Programmes in Children With Cerebral Palsy: A Systematic Review and a Metasynthesis

Child: Care, Health and Development, Volume 51, Issue 2, March 2025.
ABSTRACT Introduction One of the treatments with the greater scientific support for children with cerebral palsy (CP) are home programmes (HP). However, its implementation may be complex in some cases. A systematic review was conducted to explore the existing literature on the following question: What are the barriers and facilitators to implementing ...

Bayesian FDOA Positioning with Correlated Measurement Noise

Remote Sensing
In this paper, the problem of source localization using only frequency difference of arrival (FDOA) measurements is considered. A new FDOA-only localization technique is developed to determine the position of a narrow-band source.

Direction Finding Techniques for Over‐the‐Horizon Radars

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
The key contribution lies in the detailed simulation‐based assessment of these methods under varying signal‐to‐noise ratio (SNR) conditions using realistic waveform parameters derived from measured real OTH radar signals. The results quantitatively characterise the operational strengths and limitations of each method, offering a practical foundation ...
