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.

Enhanced Moving Source Localization with Time and Frequency Difference of Arrival: Motion-Assisted Method for Sub-Dimensional Sensor Networks

open access: yesApplied Sciences
Localizing a moving source by Time Difference of Arrival (TDOA) and Frequency Difference of Arrival (FDOA) commonly requires at least N+1 sensors in N-dimensional space to obtain more than N pairs of TDOAs and FDOAs, thereby establishing more than 2N ...

Algebraic distributed source localisation algorithm using TDOA and AOA measurements

open access: yesThe Journal of Engineering, 2019
This study proposes an algebraic distributed source localisation algorithm that combines time difference of arrival (TDOA) and angle of arrival (AOA) measurements. The proposed algorithm uses AOAs to remove the unknown parameters in TDOA equations caused

Emitter location via Kalman filtering of signal time difference of arrival [PDF]

open access: yes, 1994
A relatively simple time domain method is developed to calculate the time of arrival for radar signals. The error present in the estimate of the time of arrival for a single pulse and a burst of pulses are developed and the effects of SNR, PRF ...

PARTICLE SWARM OPTIMIZATION FOR TIME-DIFFERENCE-OF-ARRIVAL BASED LOCALIZATION

open access: yes, 2008
Time-difference-of-arrival (TDOA) based source localization has been intensively studied and broadly applied in many fields. In this paper, particle swarm optimization (PSO) is employed for positioning with TDOA measurements in the circumstances of known

An Improved Time Difference of Arrival/Frequency Difference of Arrival Estimation Algorithm for Frequency Shift Keying Signals

open access: yes
Based on the generalized cross-correlation method (GCC), the period peaks in the cross-correlation function (CCF) of frequency shift keying (FSK) signals will degrade the estimation performance of time difference of arrival (TDOA), as well as the ...
