Emitter velocity estimation comparison for frequency difference of arrival measurement based single and multiple reference lateration algorithm [PDF]

open access: yes, 2019
The accuracy at which the instantaneous velocity and position of a non-stationary emitting source estimated using a lateration algorithm depends on several factors such as the lateration algorithm approach, the number and choice of reference receiving ...

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

open access: yesIEEE 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

open access: yesLeida 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 ...

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

open access: yesChild: 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

open access: yesIET 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 ...
