Joint Optimization Algorithm for UAV Trajectory and Beamforming for NOMA‐Based Integrated Sensing and Communication (ISAC) Systems

open access: yesIET Communications, Volume 20, Issue 1, January/December 2026.
This paper investgates a unmanned aerial vehicle‐assisted non‐orthogonal multiple access‐integrated sensing and communication system, which fuses the UAV's echo signal and target position by employing the extended Kalman filter algorithum to achieve high‐precision prediction of the target trajectory.

Reliability and validity of motion sensor and radar for measuring shuttlecock velocity in badminton

open access: yesInternational Journal of Racket Sports Science
Radar doppler and inertial measurement unit are often used to analyze the projectile velocity. The aim of the present study was to analyse the reliability and validity of a specifically motion sensor (named: Zepp Tennis) and a radar (Doppler-radar gun ...

Design of a Digital Twin System for Deepwater Installation Systems

open access: yesDigital Twins and Applications, Volume 3, Issue 1, January/December 2026.
A digital twin‐based system is proposed to enhance the safety and efficiency of deepwater subsea installation by enabling real‐time monitoring, predictive analysis and intelligent decision‐making. The system integrates simulation, sensing and VR interaction to support planning and operations in complex offshore environments.

WFH: A Wideband Frequency Hopping‐Based Anti‐Jamming Navigation Signal Structure

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Given the limitations of existing satellite navigation signals in antijamming performance amid growing environmental jamming, this paper proposes a navigation signal structure based on wideband frequency hopping (WFH) modulation to enhance both antijamming capability and measurement accuracy. It further introduces the nonstationary effective carrier‐to‐
