TDOA/FDOA Geolocation with Adaptive Extended Kalman Filter

2010
In this paper, we propose a moving target tracking algorithm using the measurement signals of time difference of arrival (TDOA) and the frequency difference of arrival (FDOA). As the conventional target tracking using TDOA measurement is not accurate enough to estimate the target location, we use the TDOA and FDOA measurement signals together to ...

A quadratic constraint solution method for TDOA and FDOA localization

2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011
This paper proposes a new closed-form solution for the position and velocity of a moving source obtained from the time differences of arrival(TDOAs) and frequency differences of arrival(FDOAs) of its emitted signal arrived at a number of receivers.

Closed form Solution of Moving Source Localization Using TDOA and FDOA Measurements Under Sensor Location Errors

2024 16th International Conference on Communication Software and Networks (ICCSN)
The moving source localization is very sensitive to the knowledge of sensor locations. In this paper, we propose a two-stage closed-form method for locating a moving source by using Time Difference of Arrival (TDOA) and Frequency Difference of Arrival ...

Localization of a moving source using TDOA and FDOA measurements

Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003
A closed-form solution that estimates the position and velocity of a moving source using time difference of arrival (TDOA) and frequency difference of arrival (FDOA) measurements of a signal received by a number of sensors is developed. The method requires only two least-squares minimization stages and is not iterative.

An algebraic method for moving source localization using TDOA and FDOA measurements with receiver location errors

2024 IEEE International Conference on Signal, Information and Data Processing (ICSIDP)

Mobile Emitter Geolocation and Tracking Using TDOA and FDOA Measurements

IEEE Transactions on Signal Processing, 2010
This paper considers recursive tracking of one mobile emitter using a sequence of time difference of arrival (TDOA) and frequency difference of arrival (FDOA) measurement pairs obtained by one pair of sensors. We consider only a single emitter without data association issues (no missed detections or false measurements).
