Loop Matching Pursuit Multistation TDOA Estimation Method Based on Noncircular Signal
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The existing TDOA estimation methods based on orthogonal matching pursuit only consider the scenario of circular signal and are prone to the degradation of estimation performance due to atom misselection under small samples and low signal‐to‐noise ratio.

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

TDOA-Based Target Tracking Filter While Reducing NLOS Errors in Cluttered Environments
Sensors, 2023 We consider tracking a moving target in a wireless communication system that is based on the radio signal. Considering a bounded workspace with many unknown obstacles, we handle tracking a non-cooperative transmitter using multiple signal receivers. Here,

Reflection-Aware Sound Source Localization
, 2017 We present a novel, reflection-aware method for 3D sound localization in indoor environments. Unlike prior approaches, which are mainly based on continuous sound signals from a stationary source, our formulation is designed to localize the position ...

IET Signal Processing, Volume 2026, Issue 1, 2026.To address the issue that the traditional direct position determination (DPD) method for coprime arrays (CAs) has limited performance in scenarios with low signal‐to‐noise ratio (SNR) and small quantity of observation data, a progressive optimization method based on the averaging of redundant data from virtual array elements is proposed. This method is
