Analysis of statistical resolution limit based on Rao test
Dianxin kexue, 2017 Since the approach of analyzing statistical resolution limit (SRL) based on generalized likelihood ratio test (GLRT) has the problems of high computational complexity and isn’t easy to get the analytical formula of the detection statistics,a method for ...

GNSS Spoofing Detection Based on Ionospheric Model Deviation Monitoring
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.The deviation of TEC (DTEC) consistency between DF measurements and empirical model estimations in authentic scenarios is not zero but is predictable through ionospheric annual periodicity. However, DF spoofers typically struggle to accurately counterfeit the authentic TEC value, which can disrupt the consistency between DTEC measurements and ...

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Shipborne HFSWR has limited array aperture reducing DOA estimation accuracy. The proposed CFMDS method fuses motion‐model‐based and data‐extrapolation‐based strategies to enlarge the virtual aperture. Results show improved angle estimation performance compared to single‐strategy methods.

Detection of Unresolved Targets for Wideband Monopulse Radar
Sensors, 2019 Detecting unresolved targets is very important for radars in their target tracking phase. For wideband radars, the unresolved target detection algorithm should be fast and adaptive to different bandwidths.

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper presents the first orthonormal basis function (OBF) framework adapted for passive magnetic detection of DC current‐carrying submarine telecommunications cables, extending Anderson's dipole‐based approach to cable‐like source configurations. Two orthonormal basis functions are derived from the Biot‐Savart law and integrated into a generalised
