Different perspective of time difference of arrival averaging
2012 35th International Conference on Telecommunications and Signal Processing (TSP), 2012Any emitter can be positioned using three or more receivers in two dimensional planes and four or more receivers in three dimensional planes. The transmitter signal reaches at the receivers that synchronized each other's in different times. Using this time differences of arrival (TDOAs) hyperbolic lines of positions (LOPs) are defined and target is ...

Age differences in estimating arrival-time
Neuroscience Letters, 2004The present study examined the accuracy in extrapolating an occluded trajectory in relation to observer age. Adults and children aged 7, 10, and 13 were tested in a prediction-motion task which consisted of judging, after the occlusion of the final part of its path, the moment of arrival of a moving stimulus towards a specified position. Results showed

Robust Localization Using Time Difference of Arrivals
IEEE Signal Processing Letters, 2016We investigate a localization problem using time-difference-of-arrival measurements with unknown and bounded measurement errors. Different from most existing algorithms, we consider the minimization of the worst-case position estimation error to improve the robustness of the algorithm.

Recursive geolocation with Time Differences of Arrival
2009 IEEE 17th Signal Processing and Communications Applications Conference, 2009Geolocation has particular interest and importance in Electronic Warfare. In this work, Time Difference of Arrival (TDOA) Geolocation is studied. A recursive least squares filter based algorithm has been developed. Location estimation is updated using TDOA measurement sets from moving receivers under the assumption of fixed emitter location.

Optics Letters, 2012
We propose and experimentally demonstrate a photonic approach to the measurement of the time-difference-of-arrival (TDOA) and the angle-of-arrival (AOA) of a microwave signal. In the proposed system, the TDOA and the AOA are equivalently converted into a phase shift between two replicas of a microwave signal received at two cascaded modulators.

Asynchronous time difference of arrival (ATDOA) method
Pervasive and Mobile Computing, 2015A new method for a location service in the asynchronous wireless sensor networks is outlined. This method, which is called asynchronous time difference of arrival (ATDOA), enables calculation of the position of a mobile node without knowledge of relative time differences (RTDs) between measuring sensors.

Bias free estimation of the variance of time of arrival differences
ICASSP '84. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1985In the frequency domain estimation of Time of Arrival differences, phase data of the cross-spectrum may show correlation between frequency bins due to either insufficient time-bandwidth product or the use of a nonrectangular window on the input signal samples.

Distributed time and frequency difference of arrival tracking in clutter
2012 Workshop on Sensor Data Fusion: Trends, Solutions, Applications (SDF), 2012We consider passive surveillance using time and frequency difference of arrival signals received by mobile receiver pairs. Signals received by a pair of receivers are correlated in time and frequency, followed by a detection process. In addition to the target (emitter) measurements, we may also create a number of spurious detections in each scan.
