Calibration of Motional Frequency Spread for Wide-Band FMCW Automotive Millimeter-Wave Radar

IEEE Access, 2020
As a key module for self-driving cars and advanced driver assistant systems (ADAS), frequency modulation continuous wave (FMCW) automotive millimeter-wave (mmwave) radar has a good market prospect.

ADCC‐TFNet: Adaptive Dynamic Complex Convolution for Radar Micro‐Doppler Time‐Frequency Representation of Low‐Slow‐Small Targets

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper addresses the problem of time‐frequency representation (TFR) for radar micro‐Doppler signals of low‐slow‐small (LSS) targets under noisy and multi‐component conditions. ADCC‐TFNet is proposed to generate input‐conditioned complex kernels and enhance time‐frequency ridge continuity and concentration.

Time Synchronisation for Passive Bistatic HFSWR via Kalman‐Filtered Delay‐Locked Loop

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This paper proposes a per‐chirp time synchronisation method, FLOS‐Kalman‐DLL, for passive bistatic high‐frequency surface wave radar (HFSWR) operating under the coexistence of clock drift and atmospheric impulsive noise. The method combines fractional lower‐order statistics with a Kalman‐filtered delay‐locked loop to achieve sub‐sample synchronisation ...

SRLF‐MUSIC: Toeplitz‐Anchored Structure‐Regularised Low‐Risk Covariance Fusion for Low‐SNR Small‐Snapshot MIMO Radar DOA Estimation

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
SRLF‐MUSIC addresses low‐SNR, small‐snapshot MIMO radar DOA estimation by stabilising the covariance matrix supplied to MUSIC. The method uses a Toeplitz structural anchor and risk‐controlled covariance fusion to balance finite‐sample information and structural robustness.

Scattering‐Order‐Based Decoupling Model for TWR Building Interior Structures Extraction

IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.
This study presents a scattering order‐based model for through‐the‐wall radar that separates single‐bounce wall reflections from double‐bounce corner interactions. By applying geometric and physical optics principles to isolate corner signals, the method eliminates structural ambiguities and suppresses false artifacts.

Joint MobileViT and Knowledge Distillation Network for Hand Gesture Recognition via mmWave Radar

IET Signal Processing, Volume 2026, Issue 1, 2026.
Hand gesture recognition using mmWave radar has emerged as a promising technology for human–computer interaction (HCI), smart home systems, and the Internet of Things (IoT). However, the practical application of this technology is often constrained by the high computational complexity and significant storage demands of contemporary deep neural networks,
