In this paper, different signal processing techniques are used to evaluate the breath frequency of volunteers starting from signals measured by a body-worn ultra-wideband radar. The measurement setup is based on a time domain reflectometry technique, and comprises an ultra-wideband antenna in contact with the subject’s thorax, and a vector network analyzer. The breath frequencies, obtained applying the different processing techniques on the signal reflected from the human thorax, are compared in terms of accuracy against measures acquired by a piezoelectric belt, which is a widely adopted commercial system for respiratory activity monitoring. Finally, the different techniques are compared with each other in terms of accuracy and execution time.

Abstract

In this paper, different signal processing techniques are used to evaluate the breath frequency of volunteers starting from signals measured by a body-worn ultra-wideband radar. The measurement setup is based on a time domain reflectometry technique, and comprises an ultra-wideband antenna in contact with the subject’s thorax, and a vector network analyzer. The breath frequencies, obtained applying the different processing techniques on the signal reflected from the human thorax, are compared in terms of accuracy against measures acquired by a piezoelectric belt, which is a widely adopted commercial system for respiratory activity monitoring. Finally, the different techniques are compared with each other in terms of accuracy and execution time.
