Target localization method based on semi-definite relaxation with frequency difference of arrival
Dianxin kexueThe use of frequency measurements to achieve target positioning is characterized by low cost and high reliability. Using only frequency difference of arrival (FDOA) measurements, a precise localization method for static target position was proposed.

A method to eliminate TDOA ambiguity based on FDOA and FDOA-rate
2015 International Conference on Wireless Communications & Signal Processing (WCSP), 2015For eliminating ambiguity of time difference of arrival (TDOA) in radar passive location system, especially with a high pulse repetition frequency (HPRF), a novel method based on frequency difference of arrival (FDOA) and FDOA-rate is proposed in this paper.

Motion detection using TDOA and FDOA measurements
IEEE Transactions on Aerospace and Electronic Systems, 2001A stationary transmitter can be located using two moving receivers using time and frequency difference of arrival (TDOA/FDOA). However, transmitter motion will cause a bias on the FDOA, resulting in inaccurate locations. If motion is detected, the position is known to be inaccurate. This paper contains two algorithms for detecting motion using TDOA and

An on-the-Fly FDOA-based Target Localization System
2020 IEEE 11th Latin American Symposium on Circuits & Systems (LASCAS), 2020Differential Doppler measurements can be used to localize an emitter. The performance of this approach, also known as Frequency Difference of Arrival (FDOA), can be affected by the accuracy of frequency measurements, usually carried out by a digital receiver.

FDOA determination of ADS-B transponder signals
2012 Workshop on Sensor Data Fusion: Trends, Solutions, Applications (SDF), 2012In this paper, we investigate a Frequency Difference of Arrival (FDOA) based localization scenario with a stationary sensor network and one moving emitter. A method for Frequency of Arrival (FOA) determination of ADS-B transponder messages is introduced. The FDOA of a message received at a sensor pair can be calculated from the corresponding FOAs. This

Localization of a moving source using TDOA and FDOA measurements
Proceedings of the 2003 International Symposium on Circuits and Systems, 2003. ISCAS '03., 2003A 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.

A quadratic constraint solution method for TDOA and FDOA localization
2011 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2011This 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.

Post-Newtonian Effects in Geolocation by FDOA
2016The post-Newtonian terms included in the Frequency Difference of Arrival equation derived here by means of Synge’s world-function are considered to estimate their contribution in the precise Geolocation of passive radio transmitters at rest on the earth surface. Four of these terms are kinematical and the other two are gravitational.
