摘　　要：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.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.
