Title:
High-Resolution DEM generation by nonlocal filtering of TanDEM-X interferograms 
Abstract:
We present a nonlocal synthetic aperture radar interferometry (InSAR) filter for TanDEM-X bistatic strip map interferograms, with the goal of generating a digital elevation model (DEM) from TanDEM-X interferograms with a higher resolution and accuracy than the default product. The filter is especially tuned for DEM generation as it takes into account the local topography and phase heterogeneity. Simulations and initial real data tests confirm that it significantly outperforms boxcar averaging,...    »
