Vibration analysis is a powerful tool for structural health monitoring of critical infrastructure subjected to stresses, like environmental factors, loads, and wear over time. Using non-contact sensors avoids sensor installation and enables cost and time-efficient vibration measurements. We present a portable sensor concept based on FMCW radar technology. The system was successfully validated on a high-precision calibration system.enVibrationInfrastructureRadarFMCWCondition MonitoringSHMSignal ProcessingCiritcal Infrastructure000 Informatik, Informationswissenschaft, allgemeine Werkeconference paper
