| Popis: | A newly designed radar based on interferometry is proposed and well designed in the paper. The designed radar can detect the vibration of the railway bridge with a super-resolution and a high precision, which also has remote sensing ability. The general bridge monitoring methods are expensive and time-consuming since it is difficult to install sensors that should be directly contact with the bridge, such as accelerometer and dynamometer. Based on the designed radar, experiments are constructed on a Beijing-Tianjin Inter-City high-speed railway bridge to prove that the radar interferometry can be used to preciously and accurately monitor the railway bridge's vibration. |
