IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.An elliptical polarisation conversion metasurface (PCM) is proposed for Ka‐band applications, integrated with a high‐gain substrate‐integrated waveguide (SIW) antenna. The PCM elements feature a simple design for effective linear polarisation conversion, and simulation results show an 80.38% bandwidth with a PCR over 90%.

Modelling real‐world effects in near‐field SAR collections for compressive sensing
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.This paper develops previously published work on using compressive sensing techniques to suppress sidelobes in SAR images to develop a higher‐fidelity measurement model. Using Cranfield University's GBSAR System a series, experimental measurements are conducted, and image estimation techniques are applied to this real data.

Ambiguity and area preserving linear transformations in over‐the‐horizon radar
IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.The use of recurrent waveforms in over‐the‐horizon radar (OTHR) necessitates techniques for ambiguity resolution and manipulation. In this paper, the authors elucidate methods for systematically transforming any given waveform so that its ambiguity function is transformed by any desired area preserving the linear transformation of the delay‐Doppler ...
