摘要
In this paper, the authors propose a radar technique for building structural static testing or monitoring. The technique is based on interferometric step-frequency continuous-wave (SFCW) radar. It works synthesising microwave holographic images, and comparing pairs of holograms to obtain a deformation map. The application of the interferometric technique for structural static testing of a concrete pedestrian bridge is described. The radar-measured deformation profile has been compared with a finite element simulation of the bridge. (C) 2000 Elsevier Science Ltd. All rights reserved.
