An experimental proof of concept of time‐reversal single‐sensor acoustic source localisation: Application to partial discharges

open access: yesHigh Voltage, Volume 10, Issue 2, Page 351-361, April 2025.
Abstract In this paper, for the first time, an experimental proof of concept for utilising time reversal (TR) in the acoustic regime to localise partial discharge (PD) sources was presented using a single sensor. To achieve this, an experimental setup comprising a water tank, acoustic transducers for signal transmission and reception, and 2D scanners ...

A population Monte Carlo model for underwater acoustic telemetry positioning in reflective environments

open access: yesMethods in Ecology and Evolution, Volume 16, Issue 4, Page 775-785, April 2025.
Abstract Underwater acoustic telemetry positioning is widely used to track the fine‐scale movements of aquatic animals. In study areas near acoustically reflective surfaces, reflected transmissions may cause large detection outliers that can severely reduce the accuracy of positioning models.

Joint TDOA and AOA location algorithm

open access: yesJournal of Systems Engineering and Electronics, 2013
For the joint time difference of arrival (TDOA) and angle of arrival (AOA) location scene, two methods are proposed based on the rectangular coordinates and the polar coordinates, respectively. The problem is solved perfectly by calculating the target position with the joint TDOA and AOA location.
