Summary:Autonomous driving is a topic of great importance for our society and is expected to be introduced in the automotive market in a couple of decades. Today, vehicles can already autonomously brake and accelerate in order to avoid crashes with obstacles detected by camera and radar technology. The next step towards autonomous driving is the introduction of driver health monitoring systems. Intensive research is being conducted in this field with the goal of developing a "biometric driver seat". In this paper, an interferometric radar-based vital sign detection is presented. The aim is to investigate the applicability of radar technology for vital sign monitoring such as heartbeat and breath rate of the driver with sensors embedded in the seat. The proposed interferometric radar is based on the Six-Port receiver technique and shows excellent performance for the addressed application.
