Direction-Independent Human Activity Recognition Using a Distributed MIMO Radar System and Deep Learning
Waqar, Sahil; Muaaz, Muhammad; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2023)Modern monostatic radar-based human activity recognition (HAR) systems perform very well as long as the direction of human activities is either towards or away from the radar. The monostatic single-input single-output ... -
Human activity signatures captured under different directions using SISO and MIMO radar systems
Waqar, Sahil; Muaaz, Muhammad; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2022)In this paper, we highlight and resolve the shortcomings of single-input single-output (SISO) millimeter wave (mm-Wave) radar systems for human activity recognition (HAR). A 2 × 2 distributed multiple-input multiple-output ... -

Orientation-Independent Human Activity Recognition Using Complementary Radio Frequency Sensing
Muaaz, Muhammad; Waqar, Sahil; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2023)RF sensing offers an unobtrusive, user-friendly, and privacy-preserving method for detecting accidental falls and recognizing human activities. Contemporary RF-based HAR systems generally employ a single monostatic radar ... -
A Paradigm Shift From an Experimental-Based to a Simulation-Based Framework Using Motion-Capture Driven MIMO Radar Data Synthesis
Waqar, Sahil; Muaaz, Muhammad; Sigg, Stephan; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2024)The development of radar-based classifiers driven by empirical data can be highly demanding and expensive due to the unavailability of radar data. In this article, we introduce an innovative simulation-based approach that ... -
A Simulation-Based Framework for the Design of Human Activity Recognition Systems Using Radar Sensors
Waqar, Sahil; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2023)Modern human activity recognition (HAR) systems are designed using large amounts of experimental data. So far, real-data-driven or experimental-based HAR systems using Wi-Fi or radar systems have shown considerable results. ...
