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 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

A Tightly Coupled Fusion Positioning Method Based on Particle Filtering With Effective Particle Neighbourhood Attraction Optimisation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the limitations of existing wireless and inertial navigation systems, this paper proposes a high‐precision integrated positioning scheme based on particle filtering. The method introduces a high‐weight particle neighbourhood attraction mechanism to solve the common issue of particle degeneracy.
