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 ...

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

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

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 ...

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 ...
