Abstract
Electrocardiography is a reliable method for acquisition and recording of the heart activity. However, it can be relatively uncomfortable for the patient, due to the large number of wires needed to be attached to patient’s body. Additionally, the patient’s mobility is significantly reduced, especially if the monitoring has to be performed for an extended period of time. A possible solution to this problem is to use contactless monitoring of the heart functions. In recent years, RADAR has gradually gained prominence in the medical field because of its ability to capture heartbeat-induced torso vibrations. In this paper, we
present an algorithm for monitoring multiple user heart activity simultaneously using Single-Input Multiple-Output (SIMO) continuous-wave (CW) RADAR. In the presented approach, digital beam steering acts as a spatial filter to filter out signals coming from irrelevant directions and then the heart activity signal of the person of interest is extracted. Simulation results show that the heart activity signals of multiple users can be effectively separated and extracted using the proposed method.
