A novel DEM reconstruction strategy based on multi-frequency In SAR in highly sloped terrain

Interferometric Synthetic Aperture Radar（InSAR）has been proposed as a technique for the reconstruction of the Digital Elevation Model（DEM）,which is widely used in global terrain mapping mission[1].The DEM reconstruction methods of In SAR technique are usually based on the so-called phase unwrapping（...

Description
Summary:	Interferometric Synthetic Aperture Radar（InSAR）has been proposed as a technique for the reconstruction of the Digital Elevation Model（DEM）,which is widely used in global terrain mapping mission[1].The DEM reconstruction methods of In SAR technique are usually based on the so-called phase unwrapping（PU）operation.In highly sloped terrain,the interferometric phase gradients（IPG）of the adjacent pixels are more thanπ.
