Phase Error Suppression for Swaying Antennas in Base Station-Based Bridge Monitoring (opens in new tab)

Bridges are crucial components of urban infrastructure, requiring continuous monitoring to ensure safety and longevity. With the advancement of integrated sensing and communication (ISAC), base stations (BSs) can be leveraged for cost-effective and real-time bridge health monitoring. However, the sway of the antenna feeder system (AFS) of the BS under wind disturbances introduces phase errors in echoes, significantly degrading the accuracy of deformation estimation. To address this issue, thi...
