Abstract
- Ground-based radar interferometry, an innovative technology for surface deformation monitoring has the advantages of high-security, high-resolution, adapting to all kinds of weather conditions and so on. Ground-based radar interferometry using microwave signal as transmission signal, is susceptible to atmospheric disturbance. How to eliminate the atmospheric disturbance influence is the key to achieve high-precision monitoring. Accordingly, this article aims at developing an effective atmospheric disturbance correction model. Firstly, IBIS- L system and corner reflectors as the stable points were placed. Secondly, microwave refractive index was calculated through the atmospheric parameters. Furthermore, according to the additional displacement acquired by IBIS-L system, the radial distance, azimuth distance of corner reflectors, and microwave refractive index, the atmospheric disturbance correction model in using IBIS-L system for slope monitoring was established. Finally, the additional displacement calculated from the model is in comparison with additional displacement by IBIS-L system monitoring. Experiments show that, the model can effectively eliminate the influence of atmospheric disturbance, and ensure monitoring accuracy. [ABSTRACT FROM AUTHOR]
