An improved underwater TDOA/AOA joint localisation algorithm

open access: yesIET Communications, 2021
To solve the problem of sound source localisation in underwater sensor networks, this paper constructs a pseudo-linear equation system of time difference of arrival and angle of arrival (TDOA/AOA) and then uses the weighted least squares algorithm to ...

Prioritising research on endocrine disruption in the marine environment: a global perspective

open access: yesBiological Reviews, EarlyView.
ABSTRACT A healthy ocean is a crucial life support system that regulates the global climate, is a source of oxygen and supports major economic activities. A vast and understudied biodiversity from micro‐ to macro‐organisms is integral to ocean health.

The Location of Partial Discharge Sources Inside Power Transformers Based on TDOA Database With UHF Sensors

open access: yesIEEE Access, 2019
This paper proposes a new method to locate the partial discharge (PD) sources inside the high-voltage power transformers with ultra-high frequency (UHF) sensors, based on the time difference of arrival (TDOA) database.

New three-dimensional positioning algorithm through integrating TDOA and Newton’s method

open access: yesEURASIP Journal on Wireless Communications and Networking, 2020
Passive time difference location is an important method for passive location. There are fuzzy positioning, no solution, and low positioning accuracy with the spherical coordinate conversion method in the four-station TDOA positioning algorithm.

Speaker Diarization Based on Intensity Channel Contribution [PDF]

open access: yes, 2011
The time delay of arrival (TDOA) between multiple microphones has been used since 2006 as a source of information (localization) to complement the spectral features for speaker diarization.

Anchor Pair Selection for Error Correction in Time Difference of Arrival (TDoA) Ultra Wideband (UWB) Positioning Systems

open access: yesInternational Conference on Indoor Positioning and Indoor Navigation, 2021
Ultra wideband positioning systems typically use techniques such as two way ranging (TWR) or time difference of arrival (TDoA) to calculate the position of mobile tags.

Near‐Field Acoustic Imaging Using Fiber‐Optic Distributed Acoustic Sensing and Beamforming Techniques

open access: yesAdvanced Science, Volume 13, Issue 6, 30 January 2026.
This work introduces a beamforming‐based method to generate acoustic images from fiber‐optic distributed acoustic sensing (DAS) data. By performing 2D scanning around the sensing fiber, the approach enables near‐field imaging and localization of acoustic sources, even in regions distant from the fiber. A data‐driven DAS channel selection improves image

TranQuiL: Long Range Detection and Localization of Interference in Radio Quiet Zones

open access: yesRadio Science, Volume 61, Issue 1, January 2026.
Abstract Radio Quiet Zones (RQZs) have been established to prevent radio sources from causing harmful interference to sensitive radio telescopes, which study extremely faint cosmic radio waves. Even with strict regulations, such interference is growing due to the widespread use of consumer electronics, emitting in many different frequency bands ...

A Closed-Form Localization Algorithm and GDOP Analysis for Multiple TDOAs and Single TOA Based Hybrid Positioning

open access: yesApplied Sciences, 2019
Cellular communication systems support mobile phones positioning function for Enhanced-911 (E-911) location requirements, but the positioning accuracy is poor. The fifth-generation (5G) cellular communication system can use indoor distribution systems to
