Fusion of airborne multi-aspect InSAR data by simultaneous backward geocoding

This paper shows how multiple aspects of highest resolution airborne InSAR data can be combined by simultaneous backward geocoding of the individual aspects. Due to slant range geometry and effects like layover and shadowing, fusing multi-aspect SAR data of urban areas is not possible in image space. Therefore the fusion process is modeled via object space, enabling the exploitation of redundant observations for each height value.
