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,

A FMCW-FSK Combined Waveform for Multi-Target Detection in FMCW Radar

DEStech Transactions on Computer Science and Engineering, 2017
Frequency modulated continuous wave (FMCW) radar has been widely applied in many fields. Modulated waveform is usually designed to solve the coupling problem of range and velocity in multi-target situation. A FMCW-FSK combined waveform is proposed in this work, which takes the advantages of FMCW waveform and FSK waveform.

A Linear Active Rampart Antenna Array With Two‐Dimensional Beam‐Scanning Capability for FMCW Radar Applications

International Journal of Antennas and Propagation, Volume 2026, Issue 1, 2026.
A novel linear active rampart array that is able to steer in the azimuth plane through frequency sweeping and in the elevation plane through phase shifting has been developed. The presented system uses eight active elements and two parasitic ones to ensure consistent radiation patterns.

Multiple source frequency-modulated continuous-wave optical reflectometry: theory and experiment [PDF]

, 2010
We propose and demonstrate a novel approach to increase the effective bandwidth of a frequencymodulated continuous-wave (FMCW) ranging system. This is achieved by algorithmically stitching together the swept spectra of separate laser sources.

New Design Antenna and Optimization of S‐Band Radar Networks Using CSRR Technology

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
In this paper, a new design and analysis of a highly compact metamaterial antenna array for radar applications operating in the S‐band (2–4 GHz) is presented. To enhance the electrical and radiation characteristics of the proposed antenna, a slot was introduced into the radiating element, and a novel power divider was employed.

Proposal of multiple access FMCW radar for inter-radar interference avoidance

The Journal of Engineering, 2019
Inter-radar interference will be a crucial problem when a number of frequency modulated continuous wave (FMCW) radars are densely deployed in future, since it can cause miss detection and false detection of the target due to wideband interference and ...
