APPLICATION OF ARRAY PROCESSING TECHNIQUES IN MULTIBASELINE INSAR FOR HIGH-RESOLUTION DEM RECONSTRUCTION [PDF]
Progress In Electromagnetics Research M, 2008 This work is concerned with generating the digital elevation models (DEMs) from the SAR images of the region of interest using multiple sensor arrays that are fixed on the distributed satellites. We present an exact estimate of the unwrapped phase and the relationship between the unwrapped phase and the terrain height.

A novel 3-D reconstruction approach based on group sparsity of array InSAR [PDF]
SCIENTIA SINICA Informationis, 2018 As an advanced technology, synthetic aperture radar tomography (Tomo SAR) provides the feasibility to solve the layover problem caused by the inherent side-view mode in SAR sensors. However, the conventional nonparametric spectral estimation methods, such as truncated singular value decomposition (TSVD), are limited by the poor elevation resolution and
