The dataset contains measurements from 24 subjects, with a total of 4 minutes per subject across the Resting and Apnea scenarios. The data and parameters are stored in lightweight .mat files that can be read directly in MATLAB, and the entire dataset is about 31 MB.

Code

In this repository you can find the reference code used for the technical validation of breathing and cardiac signals sparation (VS_separation) and synchronization study (TechValidation). In addition, the script PlotVS for data visualization is also included in the repository which can be used by configuring the subject and/or scenarios which shall be viewed.

In particular, this repository also contains the code for the validation of the radar micro-motion sensing part in the paper (Test_speaker), which contains the entire process from the raw beat tone signal to the target displacement signal extraction. The raw data (Loudspeaker) acquired during the test measurement is also included.

The mmWave radar measured data were recorded by means of a high speed digitizer, which is managed by a C++ based executable. The validation code was written and tested using MATLAB R2024b for Microsoft Windows.
