Feasibility Study for Single Platform Airborne FDOA and TDOA Estimation With Unknown Source
, 2016 Direction of arrival (DOA) estimation is a well studied topic and used in many different applications. Although it is usually based on time-difference-of-arrival (TDOA) of coherent signals, it is sometimes possible to also use frequency-difference-of ...

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

Velocity measurement using the FDOA Method in ground-based radio navigation system [PDF]
, 2014 Velocity is one of the main navigation parameters of moving objects. However some systems of position estimation using radio wave measurements cannot provide velocity data due to limitation of their performance.

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

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.

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 ...
