Research on a Novel Clutter Map Constant False Alarm Rate Detector Based on Power Transform [PDF]

Radioengineering, 2022
A power transform-based clutter map constant false alarm rate (CM/PT-CFAR) algorithm is proposed to improve the detection performance to the weak target in multiple persisting targets situations.

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

IET 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.

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

IET 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.

New matrix constant false alarm rate detectors for radar target detection

The Journal of Engineering, 2019
Matrix constant false alarm rate (M-CFAR) detector based on information geometry provides a novel scheme to the detection of target in sea clutter environment for pulse Doppler radar with small bunch of pulses. The detection performance of the existing M-

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

IET 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 ...

A New Synthetic Aperture Radar Ship Detector Based on Clutter Intensity Statistics in Complex Environments

Remote Sensing
In complex environments, the clutter statistical characteristics of synthetic aperture radar (SAR) are inconstant, and the constant detection performance of a false alarm rate (CFAR) detector based on a clutter statistical model is also hard to achieve ...

Application of joint domain localised matrix CFAR detector for HFSWR

The Journal of Engineering, 2019
Target detection is one of the most important parts of high-frequency surface wave radar (HFSWR) signal processing, to find targets in noise or clutter and obtain targets’ information.

A Radar Target Feature Detection Method Based on Random Permutation of Fractional Fourier Transform Spectrum Matrix

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
Traditional coherent integration detection methods based on the fractional Fourier transform (FRFT) suffer from high redundancy and difficulty in controlling the false alarm probability during detection fusion; existing feature detection methods that utilise the maximum singular value of the FRFT spectrum matrix fail to consider the impact of spectral ...
