Foot Gesture Recognition Using High-Compression Radar Signature Image and Deep Learning
Sensors, 2021 Recently, Doppler radar-based foot gesture recognition has attracted attention as a hands-free tool. Doppler radar-based recognition for various foot gestures is still very challenging. So far, no studies have yet dealt deeply with recognition of various

Wireless Sleep Apnea Detection Using Continuous Wave Quadrature Doppler Radar
IEEE Sensors Journal, 2020 A non-contact and non-invasive physiological radar monitoring system (PRMS) is introduced. The system is based on motion detection using quadrature microwave Doppler radar, eliminating the need to place sensors on the body.

A Hybrid CNN–LSTM Network for the Classification of Human Activities Based on Micro-Doppler Radar
IEEE Access, 2020 Many deep learning (DL) models have shown exceptional promise in radar-based human activity recognition (HAR) area. For radar-based HAR, the raw data is generally converted into a 2-D spectrogram by using short-time Fourier transform (STFT).

Noise radar range doppler imaging via 2D generalized smoothed‐l0
Electronics Letters, 2021 This paper presents an algorithm to enhance the range‐Doppler imaging performance for noise radar. Traditional matched filtering based method suffers from high range and Doppler sidelobes, which makes the weak targets overwhelmed by the sidelobes of ...

Generalization Ability of Deep Learning Algorithms Trained Using SEM Data for Objects Classification
Radio Science, Volume 57, Issue 12, December 2022., 2022 Abstract This paper proposes an efficient method to determine the material of spherical objects and the location of the receiving antenna relative to the object in bi‐static measurements using supervised learning techniques. From a single observation, we compare classification performances resulting from the application of several classifiers on ...

An Adaptive Filtering Algorithm Based on Range-Doppler Information Guidance
IEEE Access, 2023 Millimetre-wave frequency-modulated continuous-wave (FMCW) radar is widely used in various scenarios. However, it is often affected by static and dynamic clutter interference, which has a negative impact on its performance.

Deep learning serves traffic safety analysis: A forward‐looking review
IET Intelligent Transport Systems, Volume 17, Issue 1, Page 22-71, January 2023., 2023 Abstract This paper explores deep learning (DL) methods that are used or have the potential to be used for traffic video analysis, emphasising driving safety for both autonomous vehicles and human‐operated vehicles. A typical processing pipeline is presented, which can be used to understand and interpret traffic videos by extracting operational safety ...
