A Method of Constructing Permanent Scatterers Network to Correct the Meteorological Disturbance by GB-SAR

Atmospheric disturbance has a great influence on the measurement accuracy of Ground-Based SAR; thus the selection of a suitable atmospheric correction method is related to the reliability and accuracy of measurement results. A whole scene atmospheric correction method using the PS atmospheric correction network is proposed, and applied in a experiment monitoring a high-risk slope under construction. The effectiveness of the meteorological correction method proposed in this paper was verified by a comparison with the results of conventional atmospheric correction method and surveying robot.
