A SIMPLE STRATEGY FOR LIFE SIGNS DETECTION VIA AN X-BAND EXPERIMENTAL SET-UP

Abstract—In this paper, a simple and effective method for Through-The-Wall (TTW) life signs detection is introduced and discussed. To this aim, a Continuous Wave (CW) Microwave Transceiver working in X-Band is adopted. The detection procedure is based on the evaluation of correlation function in frequency domain between the measured and model signals. In order to ensure the reliability, proper background removal strategies are introduced. The effectiveness of the proposed approach is shown by processing experimental data collected in a realistic TTW scenario. 1. MOTIVATIONS The contact-less detection of life signs as breathing and heartbeat activity via radar sensing [1] is a well assessed topic in medical applications [2–4] and is gaining new attention for rescue operations [5– 7] and homeland defence and security [8, 9]
