APPLICATION OF ARRAY PROCESSING TECHNIQUES IN MULTIBASELINE INSAR FOR HIGH-RESOLUTION DEM RECONSTRUCTION [PDF]

open access: yesProgress 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.
