The aim of this paper is to provide a contactless microwave sensor allowing continual remote monitoring of the heartbeat and respiratory rates. This work provides a comparative study to signal detection of heartbeat, considering different frequencies and transmission powers. In addition, a model based on cardiorespiratory measure is presented. This determines the most accurate signal processing technique for the lowest possible signal to noise ratio (SNR) values. This practical approach is a necessary step before dealing with the hardware implementation and system integration.
