N2 - MIMO Radar operating at 79GHz was used for visualization of vibration of bridges. A FM-CW MIMO radar consists from 12 Transmitting and 16 receiving antennas was used. 2D SAR images reconstruction with PRF higher than 20Hz was achieved, and we demonstrated that vibration of any points in the 2D SAR image can be obtained. We measured vibration of brides, which have different structures, namely steel, and RC concrete. We showed that the vibration mode is very different between these two bridges, and demonstrated that this system can be used for practical safety observation of social infra structures.
