Detection of Human Respiratory and Range by IR-UWB Radar

Abstract

The technology of Impulse Radio Ultra-Wide-Band (IR-UWB) radar is very promising for non-contact sensing applications, such as detecting human vital signs like heart rate (HR) and respiration rate (RR), as well as determining the location of a person. This research paper introduces a technique for detecting the respiration rate and location of a stationary human. The method involves using preprocessing techniques to improve clutter reduction and estimating the frequency domain of the signals. Low pass and bandpass filters as preprocessing methods are presented. The Fast Fourier Transform (FFT) processing method is used to determine the human RR in the frequency domain. The proposed approach is evaluated using a P440 (IR-UWB) radar and shows promising results. The experiments demonstrate that the proposed method is effective in accurately detecting the vital signs of a stationary single or multiple persons. © 2023 Elsevier B.V., All rights reserved.
