4 FAQs about [Low power radar system]

What is a short-range radar sensor?

Short-range radar sensors are, e.g., more and more employed for wireless distance measurement and vibration-monitoring in industrial as well as medical appli-cations . Some of these tasks require particularly energy-efficient devices, especially when they are operated in an always-on scenario.

Can continuous wave radar be energy-efficient?

Main objective was to perform research on energy-efficient continuous wave radar systems to build next-generation systems with highly accurate absolute distance measurements and an aimed average power consumption in the one-digit milliwatt range or even lower.

Who wrote optimized signal generation for low-power multi-tone radar systems?

F. Lurz, P. Hofstetter, S. Lindner, S. Linz, F. Michler, R. Weigel, and A. Koelpin, “Optimized signal generation for low-power multi-tone radar systems,” in European Microwave Conference (EuMC), 2017, (submitted).

What is a continuous wave radar approach?

A continuous wave (CW) radar approach was chosen as it requires neither a high band-width nor complex signal processing routines. Especially sys-tems based on microwave interferometry can be implemented very energy-efficiently as the whole receiver can be realized by passive planar microwave structures and diode power detectors .
