A new phase unwrapping processing chain for 3D reconstruction using very high resolution multi-baseline data is proposed. The algorithm exploits both amplitude and phase of the available multi-baseline complex data to unwrap and simultaneously regularize the observed data. Indeed, the exploitation of amplitude data within the unwrapping chain helps in preserving sharp discontinuities, typical of urban areas. Furthermore, the algorithm is able to efficiently manage independent multi-baseline phase contributions artifacts such as the offsets. As result, the technique provides accurate and reliable DEM of the observed areas, becoming an effective and practical instrument for 3D mapping of urban areas.
