Description
Vital sign monitoring using radar technologies is a novel area of research fueled by demand for contactless and continuous health monitoring devices.
Many kinds of radar and signal processing techniques are being explored for this purpose, but success has been limited, especially when using low-cost, low-effort, and open-source techniques.
We developed an approach to monitor heart and respiratory rate using GNU Radio and a commercial-off-the-shelf (COTS) software-defined radio (SDR).
SDRs provide an efficient and affordable mechanism to rapidly prototype and validate a variety of radar and signal processing systems.
To demonstrate the viability of our approach, we use an Ettus X310 to implement a Doppler-only, bi-static radar system that transmits a continuous-wave (CW) tone at a center frequency of $4$ GHz.
We use GNU Radio signal processing blocks to extract the heart and respiratory rate of a subject in the radar's field of view and compare the estimates to a traditional heart rate monitor and respiratory rate counter.
In several experimental trials, we demonstrate that the proposed technique successfully extracts the respiration rate and estimates the heart rate to within $\pm$ 5 BPM of a traditional heart rate monitor.
