Abstract

Atmospheric disturbance can strongly influence the accuracy of Ground-Based synthetic aperture radar (GB-SAR) differential interferometry. In this paper, an atmospheric disturbance correction algorithm based on corner reflector is proposed. In order to testify the capability of the algorithm, we made an experiment of GB-SAR interferometric measurement of trihedral corner reflector displacement with atmospheric disturbance correction, and then compared the corrected result with the compensation algorithm based on meteorological parameter. The experimental results show that the correction method is reliable and precise.
