Joint Direction-of-Arrival and Time-of-Arrival Estimation With Ultra-Wideband Elliptical Arrays [PDF]

open access: yesIEEE Transactions on Wireless Communications, 2022
This paper presents a general technique for the joint Direction-of-Arrival (DoA) and Time-of-Arrival (ToA) estimation in multipath environments. The proposed ultra-wideband technique is based on phase-mode expansions and the use of nearly frequency ...

Local Strong Convexity of Source Localization and Error Bound for Target Tracking under Time-of-Arrival Measurements [PDF]

open access: yesIEEE Transactions on Signal Processing, 2021
In this paper, we consider a time-varying optimization approach to the problem of tracking a moving target using noisy time-of-arrival (TOA) measurements.

Semidefinite Programming Algorithms for 3-D AOA-Based Hybrid Localization

open access: yesIEEE Open Journal of Signal Processing, 2023
By taking different kinds of measurements at the same time, it may be possible to improve the accuracy of target localization or reduce the number of sensors needed.

A comparative analysis of pulse time-of-arrival creation methods [PDF]

open access: yesAstronomy & Astrophysics, 2021
Extracting precise pulse times of arrival (TOAs) and their uncertainties is the first and most fundamental step in high-precision pulsar timing.

Self-Calibration for the Time-of-Arrival Positioning

open access: yesIEEE Access, 2020
Self-calibration of time-of-arrival positioning systems is made difficult by the non-linearity of the relevant set of equations. This work applies dimension lifting to this problem.

ToA-TS: Time of arrival based joint time synchronization and tracking for mobile underwater systems [PDF]

open access: yesAd Hoc Networks, 2015
Time synchronization and localization are key requirements for distributed underwater systems consisting of numerous low-cost submersibles. In these systems, submersibles are highly resource constrained and typically have limited acoustic communication capability.

Time-of-arrival distributions from position-momentum and energy-time joint measurements [PDF]

open access: yes, 1999
The position-momentum quasi-distribution obtained from an Arthurs and Kelly joint measurement model is used to obtain indirectly an ``operational'' time-of-arrival (TOA) distribution following a quantization procedure proposed by Kocha\'nski and W ...

Statistical Characterization and Mitigation of NLOS Errors in UWB Localization Systems [PDF]

open access: yes, 2011
In this paper some new experimental results about the statistical characterization of the non-line-of-sight (NLOS) bias affecting time-of-arrival (TOA) estimation in ultrawideband (UWB) wireless localization systems are illustrated.

Double sliding window variance detection-based time-of-arrival estimation in ultra-wideband ranging systems

open access: yesInternational Journal of Electrical and Computer Engineering (IJECE), 2022
Ultra-wideband (UWB) ranging via time-of-arrival (TOA) estimation method has gained a lot of research interests because it can take full advantage of UWB capabilities. Energy detection (ED) based TOA estimation technique is widely used in the area due to
