Abstract
This dataset comprises radar-acquired signals from 15 subjects walking on a treadmill, aimed at exploring methodologies for non-contact vital sign detection under conditions of significant body movement. Each subject participated in four experimental sessions, where radar data were collected using two Continuous Wave (CW) radars positioned to capture signals from the front and back of the subject. The data includes both raw and demodulated signals synchronized with ground-truth data obtained from a BioPac system. The radar signals were processed to mitigate the effects of body movement, a significant source of noise in such applications. This dataset provides a valuable resource for researchers interested in developing and validating algorithms for vital sign monitoring in dynamic environments, offering potential applications in healthcare, sports, and other fields where continuous monitoring of physiological parameters is essential.
The dataset is organized in a main folder, which includes an Excel spreadsheet detailing subjects’ information such as gender and BMI. This folder is further subdivided into folders corresponding to individual subjects. Each subject’s folder is divided into four sections, each representing one of the experiences performed by the subject. Within these folders, there is one .txt file named testX, where X denotes the experience number, containing the ground-truth data. Additionally, two .mat files are included. These files encompass a 3-minute interval during which walking was performed. The synched.mat file contains the demodulated signals, and the synched complex.mat file includes the raw data. These .mat files comprise three arrays corresponding to the synchronized data acquired from the front and back radars, as well as the ground-truth device. All the data is sampled at 100Hz.
