| Abstract: | The stepped-frequency continuous wave technology and interferometric techniques combine to form the terrestrial microwave interferometer radar system GB-radar, used to obtain high-precision, high-resolution deformation information can be realized on ground targets static and dynamic precision monitoring. This paper introduces the technology based IBIS- S system in bridge deformation monitoring applications, analysis of measurement error, verified by examples terrestrial microwave radar interferometry technique can subtly change the dynamic bridge deflection measurement, high precision, can truly reflect the dy- namic characteristics of structures. |
