Vibrations Monitoring for Highway Bridge Using mm-Wave Radar

摘要

Bridge vibration monitoring is very important since many bridges are constructed every year. To obtain full range, all weather and real-time bridge vibrations, a mm-wave radar is devised and used for monitoring the micro-deformation of these bridges. The measured results show that the designed mm-wave radar can well monitor the vibrations of the highway bridges with a super-resolution and high precision. Thus, the designed radar can be used for natural disaster monitoring, such as bridge monitoring, dam monitoring, debris flow monitoring applications.
