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.

Improved Scattering Center Extraction From ISAR Data Using Simplex Optimization
International Journal of Antennas and Propagation, Volume 2025, Issue 1, 2025.Inverse synthetic‐aperture radar (ISAR) techniques have started to play a key role in calculating the radar cross‐section (RCS) values of objects from near‐field measurements. It is assumed that the scene (or the scatterer) is composed of scattering centers (SCs) whose locations and complex amplitudes are found from the ISAR data.

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.

Polarisation variation of linear polarised Bi‐ISAR system in space targets imaging
IET Radar, Sonar & Navigation, 2021 A bistatic inverse synthetic aperture radar (Bi‐ISAR) system is used to observe space targets through different viewing angles via a bistatic radar configuration. It is seen that the receiver of a linear polarised Bi‐ISAR system with a long baseline will

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 ...
