Forest Diff-Tomo Functionalities: Tests of Robust Tomography and Separation of Dynamic Processes

Inhalt:
Techniques based on the coherent combination of complex (i.e. amplitude and phase) SAR data can extract rich information on complex scenarios with multiple scatterers mapped in the SAR cell. Multipass/multibaseline “4D” Differential Tomography is a promising advancement in this field, furnishing space-time signatures of multiple scatterer dynamics in the SAR cell. Evolutions and extended P-band tests are presented of new recently derived Diff-Tomo based functionalities for the separation of heights, temporal decorrelation mechanisms, and deformation velocities in forest scenarios, characterized by a temporal decorrelating canopy scatterer, in layover with a ground scattererer, possibly subsiding.
