Abstract

The authors analyse different techniques for 3D SAR mapping. Interferometry using narrow-band SAR enables retrieval of topography but gives an ambiguous height. Stereoscopy can also be used but has degraded resolution due to speckle. For ultra-wide band SAR, i.e. wavelength-order resolution, these techniques converge and give similar vertical resolution. A significant advantage, however, is that the interferometric height becomes unambiguous since the depth of focus is only one fringe
