Title:
Improving {TanDEM}-X {DEMs} by Non-local {InSAR} Filtering
Abstract:
The standard {TanDEM}-X product meets {HRTI}-3 {DEM} specification and comes with a sample spacing of 12 m. In this paper we apply non-local means ({NL}) interferogram filtering to the {TanDEM}-X data. Our version of the {NL} filter is a modification of the original formulation and provides better noise reduction. Based on simulations, phase noise reduction, coherence estimation accuracy and spatial resolution of our {NL} filter are compared to conventional filters. Finally, the first {TanDEM}-X...    »
