Tidal flat digital evelvation model (DEM) construction by means of TanDEM-X

This study will explore the feasibility of TanDEM-X interferometric observations in tidal flats. The bi- and monostatic modes of TanDEM-X give us the great possibility for interferometric SAR (InSAR) technique to generate highly accurate intertidal DEM due to no time lag (bistatic case) or approximately 10-second temporal baseline (monostatic case) between master and slave SAR image acquisitions. The TanDEM-X DEM in tidal flats will be validated against RTK-GPS measurements and topographic information measured from UAV system.
