Abstract

In August 2009, the TropiSAR campaign was conducted in French Guiana with the ONERA airborne system SETHI in order to support the Phase A of the Earth Explorer candidate mission, BIOMASS. Several SAR data acquisitions at P-band are now available for analysis over tropical forest. This paper presents one of the four acquisition sites, Paracou and two related studies performed over this dataset. The first interrogation focuses on the radiometric stability at P-band of the forest backscatter. This stability is an essential point if the backscatter is expected to be used for forest biomass estimation. Moreover, the compatibility of the current BIOMASS mission design, relying on repeat pass interferometry for forest height retrieval, to tropical forest and the related temporal decorrelation is then explored.
