Deep Learning‐Based End‐to‐End Target Detection for Active Sonar With Frequency‐Domain Input

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper introduces SSA‐Net, a novel end‐to‐end deep learning framework that bypasses conventional beamforming and matched filtering for active sonar target detection. The model directly maps raw multichannel frequency‐domain data to azimuthal detection probabilities using a specialised architecture with decoupled convolutional and spatial attention ...

Impact of Common Indoor Materials on 77–81 GHz mmWave Radar Performance: Signal Behaviour, Attenuation and Reflection Characteristics

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper investigates the impact of common indoor materials on mmWave radar signal behaviour at 77–81 GHz. Experimental results quantify material‐dependent attenuation and reflection effects under line‐of‐sight and non‐line‐of‐sight scenarios, providing actionable guidance for radar deployment and indoor sensing applications.

A Study of Selected Constant False Alarm Rate (CFAR) Detectors for Vessels with Compact and Dual Polarimetric Synthetic Aperture Radar (SAR)

open access: yesCanadian Journal of Remote Sensing
Space-based polarimetric synthetic aperture radar (SAR) plays an important role in wide-area maritime surveillance and vessel detection. Traditionally, dual polarimetric (DP) SAR has been preferred for such applications, but compact polarimetric CP SAR is a newer option that potentially offers improved backscatter characterization of targets. There are

Joint Beam and Power Allocation for Cooperative Jamming in Terrain‐Constrained Environments

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study addresses the critical challenge of aircraft formation cooperative jamming against networked radar systems (NRS) in complex electromagnetic and geographical environments. We believe this work aligns well with your journal's focus on advanced remote sensing technologies, signal processing and the analysis of complex environmental interactions.

Performance evaluation of CA-, GO- and SO-CFAR processors in a non-centered Lévy-distributed clutter

open access: yesMajlesi Journal of Electrical Engineering
Constant false alarm rate (CFAR) processors are critical for radar reliable target detection in radar systems. Traditional CFAR designs often assume Gaussian clutter, which may not reflect real-world conditions.

Single‐Channel Multi‐Component Linear Frequency Modulation Signal Blind Separation Based on Multi‐Feature Enhanced Swin‐Transformer

open access: yesIET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
To address the underdetermined blind source separation problem of single‐channel multi‐component linear frequency modulation (LFM) signals, the separation task is reformulated as a semantic segmentation problem on time‐frequency spectrograms. A multi‐feature enhanced Swin‐Transformer network, integrating an optimised convolutional block attention ...
