BIOMASS Tomography: Temporal Decorrelation Performance in the Tropical Forest

Inhalt:
The objective of this paper is to provide a better understanding of the impact of temporal decorrelation on BIOMASS tomographic processing. This was evaluated by generating a BIOMASS data stack that accounts for both the 6 MHz bandwidth limit and temporal decorrelation. To this aim, we developed a simulator, which allows us to generate a temporal BIOMASS data stack by combining 3-D high resolution data from TropiSAR and the temporal decorrlation from TropiScat data-sets. The resulting tomograms and forest heights were observed to change acceptably as long as the revisit time is 4 days or less. Therefore, the revisit time for the BIOMASS tomographic phase at 3-4 days as proposed should be feasible.
