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.

Underground personnel positioning system based on ultra wideband technology
In view of problems of short transmission distance, poor anti-multipath effect and low positioning accuracy existed in current underground personnel positioning technologies, an underground personnel positioning system was proposed by use of ultra ...

Algebraic distributed source localisation algorithm using TDOA and AOA measurements
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]
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
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
