Statistical Analysis of Performance of Optimisation‐Based SAR Autofocus
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.Transionospheric SAR autofocus is a variational algorithm designed to overcome the limitations of conventional autofocus methods in correcting ionospheric distortions in spaceborne SAR images. This study provides a systematic statistical analysis of its robustness, examining the effects of turbulence, clutter, and noise on performance.

Inverse Airborne Optical Sectioning
Drones, 2022 We present Inverse Airborne Optical Sectioning (IAOS), an optical analogy to Inverse Synthetic Aperture Radar (ISAR). Moving targets, such as walking people, that are heavily occluded by vegetation can be made visible and tracked with a stationary ...

Analysis for sparse channel representation based on dictionary learning in massive MIMO systems
IET Communications, Volume 18, Issue 20, Page 1728-1740, December 2024.We provide a qualitative analytical formula for dictionary sparse representation accuracy and establish an optimal upper bound. Abstract The accuracy analysis of dictionary sparse representation for channels in massive MIMO systems is a relatively unexplored field.

A method of 2D and 3D display of radar terminal base on programmable pipeline
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2513-2520, December 2024.In contrast to the ideal 3D display for meteorological radar, there is no 3D mode in the military engineering field. How to realise the 2D and 3D display for general radar terminal efficiently using the local graphics processing unit (GPU), which is impossible to realise with the traditional method of field programmable gate array now, has became an ...

Near‐field scattering centre modelling for complex targets
IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2657-2666, December 2024.In this paper, the authors presented the near‐field scattering centre model with the dependence description of radar distance. The model can be used to quickly calculate the near‐field scattering field and radar image features of complex targets. Abstract The parametric scattering centre (SC) model of the target has been widely used in the rapid ...
