On Models and Approaches for Human Vital Signs Extraction from Short Range Radar Signals

no code implementations15 Apr 2024 Mikolaj Czerkawski, Christos Ilioudis, Carmine Clemente, Craig Michie, Ivan Andonovic, Christos Tachtatzis

The paper centres on an assessment of the modelling approaches for the processing of signals in CW and FMCW radar-based systems for the detection of vital signs.

On Input Formats for Radar Micro-Doppler Signature Processing by Convolutional Neural Networks

no code implementations12 Apr 2024 Mikolaj Czerkawski, Carmine Clemente, Craig Michie, Christos Tachtatzis

Convolutional neural networks have often been proposed for processing radar Micro-Doppler signatures, most commonly with the goal of classifying the signals.

A Novel Micro-Doppler Coherence Loss for Deep Learning Radar Applications

no code implementations12 Apr 2024 Mikolaj Czerkawski, Christos Ilioudis, Carmine Clemente, Craig Michie, Ivan Andonovic, Christos Tachtatzis

Deep learning techniques are subject to increasing adoption for a wide range of micro-Doppler applications, where predictions need to be made based on time-frequency signal representations.

Robustness of Deep Neural Networks for Micro-Doppler Radar Classification

no code implementations21 Feb 2024 Mikolaj Czerkawski, Carmine Clemente, Craig Michie, Christos Tachtatzis

Both small temporal shifts and adversarial examples are a result of a model overfitting on features that do not generalize well.

Major TOM: Expandable Datasets for Earth Observation

no code implementations19 Feb 2024 Alistair Francis, Mikolaj Czerkawski

If ever larger datasets are to be built, and duplication of effort minimised, then a shared framework that allows users to combine and access multiple datasets is needed.
