Loop Matching Pursuit Multistation TDOA Estimation Method Based on Noncircular Signal
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 Hybrid AOA and TDOA-Based Localization Method Using Only Two Stations
Target localization plays an important role in the application of radar, sonar, and wireless sensor networks. In order to improve the localization performance using only two stations, a hybrid localization method based on angle of arrival (AOA) and time ...

Two-dimensional precise positioning method of coal mine field personnel
Aiming at the slow speed of two-dimensional accurate positioning of TOF in coal mine sites, a two-dimensional positioning method based on TOF combined with TDOA was proposed to meet the needs of rapid localization in coal mine sites.

Example of cluster identification of attitude configurations to avoid in the attitude space (in terms of angles of roll, pitch and yaw) for a payload composed by a cross antenna array with angle of arrival technology for CubeSats platforms. ABSTRACT Satellite geolocation of radio‐frequency emitters increasingly relies on compact angle‐of‐arrival (AOA ...

Reflection-Aware Sound Source Localization
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 ...

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.

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

Map-Aware Models for Indoor Wireless Localization Systems: An Experimental Study
The accuracy of indoor wireless localization systems can be substantially enhanced by map-awareness, i.e., by the knowledge of the map of the environment in which localization signals are acquired.
