Time Difference of Arrival Estimation Based on a Kronecker Product Decomposition
IEEE Signal Processing Letters, 2021Time difference of arrival (TDOA) estimation, which often serves as the fundamental step for a source localization or a beamforming system, has a significant practical importance in a wide spectrum of applications. To deal with reverberation, the TDOA estimation problem is often transformed into one of identifying the relative acoustic impulse ...

Indoor Localization Using 802.11 Time Differences of Arrival
IEEE Transactions on Instrumentation and Measurement, 2016This paper proposes a novel time-based method for determining the position of an IEEE 802.11g transmitter using multiple mutually synchronized 802.11g receivers. By means of baseband signal processing, the proposed algorithm obtains a high-resolution estimate of the time of arrival (TOA) of the long training sequence symbol at each receiver.

Geolocation by time difference of arrival using hyperbolic asymptotes
2004 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2004The paper proposes a new simplified algorithm to estimate the location of an emitter by utilizing time difference of arrival (TDOA) measurements. This is achieved by recasting the estimation problem in prolate spheroidal coordinates. Prolate spheroidal coordinates greatly simplify the TDOA equations, producing a set of linear equations in the far field

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.

Array Shape Observability From Time Differences of Arrival
IEEE Transactions on Aerospace and Electronic Systems, 2011In this paper, we study the observability conditions for the relative position of a set of passive sensors from the measured time differences of arrival (TDOA) of signals from a set of noncooperative sources lying in the same plane. The sources are broadband to measure the TDOA and far enough to consider each source is detected in the same line of ...

Robust Self-calibration of Constant Offset Time-difference-of-arrival
ICASSP 2019 - 2019 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2019In this paper we study the problem of estimating receiver and sender positions from time-difference-of-arrival measurements, assuming an unknown constant time-difference-of-arrival offset. This problem is relevant for example for repetitive sound events. In this paper it is shown that there are three minimal cases to the problem. One of these (the five

Navigation from time differences of arrival
The Journal of the Acoustical Society of America, 2004A brief history and a few modern developments are given for hyperboliclike navigation systems in which location is estimated from measurements of the difference in the propagation time of a signal from two or more known locations. Today, hyperbolic navigation is used in locating ships, calling animals, GPS receivers, cellular telephones, and other ...

Passive radar localization by time difference of arrival
MILCOM 2002. Proceedings, 2003A detailed analysis for the performance of TDOA based passive radar localization systems is provided. The system considered in the analyses consists of four sensors and associated receiver blocks, samplers, and signal processors. Arrival time for the radar pulses is obtained by adaptive thresholding. Cramer-Rao bounds of TOA and TDOA are obtained.

Time Difference of Arrival Enhancement with Ray Tracing Simulation
2018A Hybrid technique is proposed to improve the Time Difference of Arrival (TDoA) Localization systems in Non-line of Sight situation. A Ray tracing simulation tool is used to extract the time of arrival difference characteristic from the environment and binding with the TDoA a multilateration sensor scheme to estimate the position of an electromagnetic ...

Estimation of time differences of arrival by pole decomposition
IEEE Transactions on Acoustics, Speech, and Signal Processing, 1983Time differences of arrival (TDOA's) of emitter wave fronts to a spatially distributed array of sensors can be used to determine the source location. In this paper, we suggest a new method of TDOA estimation for multiple unknown autoregressive moving average (ARMA) sources and additive noise that may be correlated between the sensors.
