Název v původním jazyce

Qualitative distinction between terrain deformations and processing errors, and quantitative description of deformations for the 3-pass interferometry

Popis výsledku v původním jazyce

The 3-pass interferometry means that we use three scenes where one pair (topo pair) is considered to have no influence on a deformation. The DEM is already derived in radar coordinates from this pair, and consequently this influence is also subtracted from deformation pair (deformation pair). The topo interferogram must be unwrapped first and then rewrapped in order to have the same height ambiguity as the deformation interferogram. This method is used to remove the topographically induced phase from the interferogram containing topography, deformation and atmosphere. The perpendicular baseline of the topo pair should be longer than that of the deformation pair to prevent that noise is multiplied. The advantage of the 3-pass interferometry is the factthat the whole processing is performed in the master slant range coordinate system and only the coregistration of complex SAR images is necessary. Both pairs (topo and deformation pair) have the same master scene.
