An effective localization algorithm for moving sources
By utilizing the time difference of arrival (TDOA), the frequency difference of arrival (FDOA), and the differential Doppler rate (DDR) measurements from sensors, this paper proposes an effective moving source localization algorithm with closed solutions.

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 ...

Robust TDOA/FDOA estimation from emitter signals for hybrid localization using UAVs
This paper considers the time difference of arrival (TDOA) and frequency difference of arrival (FDOA) estimation problem for joint localization using unmanned aerial vehicles (UAVs), involving range migration (RM) and Doppler ambiguity within observation

Non‐Coherent Synthetic Aperture Passive Source Localisation
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

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
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.

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 ...
