Sensors allow the automation of production and logistic processes and are consequently the foundation for effective added value. Precise sensor technology forms a cornerstone for industry 4.0. To date, radar-based sensors play a tangential role in industry. Yet, their advantages are evident: Compared to optical sensors, radar systems are unaffected by challenging visual conditions and, opposed to X-rays, they pose no threat to health. The Fraunhofer Institute for Applied Solid State Physics IAF develops compact and high-resolution radar systems, which can significantly increase the efficiency of different industrial processes. The newest technologies will be shown at Hannover Fair 2019 (Hall 2, Booth C22), from April 1-5.
