GPS-InSAR Integrated Deformation Model with Additional Systematic Parameters for Three-Dimensional Deformation Fields
Abstract Considering the systematic differences between InSAR monitoring deformation and GPS observation, an integrated deformation analysis model with additional systematic parameters is established for the three-dimensional deformation field, in order to integrate GPS and InSAR data effectively. In this model, systematic parameters are added under the constraint of high accurate deformation derived from GPS to compensate system error in InSAR derived deformation. Both simulated and measured data prove the significance of our method in improving the accuracy of three deformation components, especially in U direction.
