Robust Beamforming for ISAC Systems via Probability of Detection Optimisation
Electronics Letters, Volume 62, Issue 1, January/December 2026.We propose a two‐step robust beamforming design for ISAC that maximises multi‐target detection probability while satisfying multi‐user SINR and per‐antenna power constraints. A sensing‐only Riemannian optimisation on the oblique manifold shapes the transmit covariance, followed by SDR‐based reconstruction to enforce communication guarantees ...

FDA‐MIMO Range and Angle Estimation Based on Hybrid Tensor Ring and CP Decomposition
Electronics Letters, Volume 62, Issue 1, January/December 2026.The graphical abstract illustrates the RMSE performance of range and angle estimation versus SNR for different array configurations. The proposed method consistently achieves lower estimation error than existing approaches and closely matches the Cramér‐Rao bound across the entire SNR range, demonstrating its superior accuracy.

Low‐Complexity DOA Estimation: Combining VSSLMS With FFT Spectrum Estimation
Electronics Letters, Volume 62, Issue 1, January/December 2026.This letter presents a novel, low‐complexity framework for DOA estimation. The proposed method achieves a significant reduction in computational complexity—from O(ML) to O(M log L)—compared to conventional SSE methods. Crucially, as illustrated in the accompanying figure, the method maintains high estimation accuracy, outperforming standard SSE‐based ...

Ultra‐Wideband Coupled‐Fed Loop Antenna Pair for 5G Mobile Terminals
IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.This paper presents an ultra‐wideband (UWB) antenna pair for 5G mobile terminals. The UWB antenna pair is composed of two coupled‐fed loop antennas with a common shorted branch, which achieves a compact size. The experimental results show that the MIMO array covers 3.3–7.8 GHz with a relative bandwidth of 81.08%, and the isolation between ports is ...

Multispectrally Constrained Waveform Design for MIMO Radar Direction Finding
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.This paper focuses on the design of transmit waveforms for multiple‐input‐multiple‐output (MIMO) radar systems in a spectrally crowded environment. The purpose is to improve the angle estimation performance of MIMO radar by minimising the asymptotic estimation bound of multiple signal classification (MUSIC) algorithm.
