Summary

In general, four main steps should be carried out:

  • Estimation of non-linear deformations at a water reservoir
  • Comparison of different multi-baseline InSAR processing methods
    • Traditional PSInSAR
    • Traditional PSInSAR including a deformation model based on water level changes in the reservoir
    • StaMPS based approach for estimating deformations not related in time as implemented in WhuPsi
    • SBAS based approach probably more suitable for the suburban nature of the scene but with an estimated loss of resolution and accuracy
  • Analysis of the model based approach for linearizing non-linear deformations and validation
  • Three dimensional motion estimation by combination of deformations estimated from TerraSAR-X stripmap data (descending) and Sentinel-1 IW data (ascending)

The project is funded by the National Natural Science Foundation of China (Grant No. 41174120) as well as internal funding of LIESMARS.
