Collaborative Beamforming for Multi‐Target Localization Using Passive Anchors

Electronics Letters, Volume 62, Issue 1, January/December 2026.
A joint collaborative beamforming strategy for passive sensor network is proposed active sensors generate collaborative beam to power up the passive sensors and attain accurate self‐localization. ABSTRACT Using wireless passive sensor nodes as anchors is a cost‐effective way for localization system.

A 3D Non‐Stationary Wideband GBSM for Low‐Altitude UAV Channels in Rail Environments

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This paper presents a three‐dimensional (3D) wideband non‐stationary Geometry‐Based Stochastic Channel Model (GBSM) for low‐altitude unmanned aerial vehicle (UAV) communications. Distinct from existing modelling frameworks, the proposed model integrates air‐to‐air (A2A) and air‐to ground (A2G) scenarios into a generalised channel model. Moreover, a two‐

A Fuzzy-Based Angle-of-Arrival Estimation System (AES) Using Radiation Pattern Reconfigurable (RPR) Antenna and Modified Gaussian Membership Function

IEEE Access, 2019
Angle-of-arrival (AOA) estimation is an important factor in various wireless sensing applications, especially localization systems. This paper proposes a new type of AOA estimation sensor node, known as AOA-estimation system (AES) where the received ...

Joint Time Synchronisation and Localisation Method by TDOA Observation in 5G Networks

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This work proposes a method for joint time synchronisation and localisation problems and proposes to obtain the initial values of the alternating iteration algorithm through solving the MVIE problem. The simulations showcase the satisfying positioning accuracy and clock synchronisation accuracy of the proposed method.

Controlling AoA Estimation Errors in Rician Fading via Measurement Quality Classification

IEEE Access
Angle of Arrival (AoA) estimation plays a crucial role in modern positioning systems but is often affected by errors in multipath channels. Existing methods typically lack a direct mechanism to assess the quality of the estimates, while full channel ...

Performance of Angle of Arrival Detection Using MUSIC Algorithm in Inter-Satellite Link

, 2018
An attitude of satellite is not always static, sometimes it moves randomly and the antenna pointing of satellite is harder to achieve line of sight communication to other satellite when it is outage by tumbling effect.

Predicting and Clustering Attitude‐Induced Divergence in Cross‐Array AOA Measurements for LEO Satellites

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
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 ...
