%X Interferogram images derived from spaceborne synthetic aperture radar system exhibit artifacts due to noise and atmospheric effects,which may mitigate the accuracy of the result DEM. In this paper,we present a method to combine uncorrelated topographic profiles generated by multi-temporal interferometric SAR data,this weighted combination is carried out in wavelet domain, which estimates the distortion power,of noise and atmosphere and improves the accuracy of final DEM with interferofram images of Shangyi area, Hebei province as test data.
