What was the purpose of INDREX-2?

The objective of INDREX-II: Indonesian Radar Experiment Campaign over Tropical Forest in L- and P-band was to:

  • build up a data base for the investigation and validation of bio-/geophysical parameters obtained from L- and P-band polarimetric SAR interferometry (Pol-InSAR) acquired over tropical forests
  • to secure with this data set feedback to the European Agency regarding the optimal SAR sensor configuration and algorithms for biomass retrieval and monitoring in tropical areas.

What was the outcome of INDREX-2?

INDREX-II was a successful campaign in terms of experiment planning, radar data and ground measurement acquisition and radar data quality. All suggested experiments could be performed as described in the Experimental Plan submitted to ESA. The planned time schedule could be kept and no major technical problem occur during the INDREX-II campaign.
