A Combined Navigation Fault Detection Method Based on Wavelet‐ResNet
Electronics Letters, Volume 61, Issue 1, January/December 2025.A combined navigation dataset, using wavelet transform is constructed and a residual network structure is trained for fault detection. The results show that this method can effectively improve the training efficiency and the accuracy of slowly varying faults.

A Student's T Distribution‐Based Filter Design for SINS/GNSS With Heavy‐Tailed Noise
IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.To reduce the affection of outliers caused by heavy‐tailed noise, the noise model is constructed by the Student's T distribution rather than the Gaussian distribution, and the related probability density functions (PDF) are adaptively modelled as student's T PDFs with different DoF parameters.

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This work explores underwater TMA by incorporating time delay and Doppler frequency measurements along with angle data, eliminating the need for own‐ship manoeuvre and improving estimation accuracy in presence of non‐Gaussian sensor noise. Furthermore, since the own‐ship's position is inherently uncertain due to navigation errors, this work addresses ...

Multiframe Target Localization With Strapdown Seeker Based on Self‐Adaptive L‐SHADE
International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.Strapdown seekers are increasingly used in the terminal guidance for the advantages of small size and low cost. However, due to the coupling of the seeker with the missile and its limited field of view, there is a risk of losing the target. This paper proposes a multiframe fusion target localization method for missiles with strapdown seekers, which can
