A method for localization TDOA estimation based on signal‐level fusion and analysis

Electronics Letters
Passive localization using time difference of arrival (TDOA) is one of the common methods for radiated source target localization, and its localization performance depends on the accuracy of TDOA estimation. In many localization scenarios, the signals of

Reducing Bias for Closed‐Form TDOA Localization in Unified Near‐Field and Far‐Field Model

IET Signal Processing, Volume 2026, Issue 1, 2026.
Bias is a fundamental metric for evaluating the average error of an estimator, where lower bias indicates an estimator closer to the true value. Recent studies on time difference of arrival (TDOA) localization have introduced the modified polar representation (MPR) to unify near‐field and far‐field scenarios, enhancing robustness to the source range ...

Seismo‐Acoustic Detection and Localization of Iceberg Collapse in Atka Bay, Antarctica

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract On 12 January 2022, an iceberg collapsed at the edge of frozen Atka Bay, Antarctica. The event generated seismic, hydroacoustic, and atmospheric infrasound waves recorded by a local network comprising land‐ and iceshelf‐based seismometers, an underwater hydrophone, and an on‐ice infrasound array.
