The AfriScat campaign is designed to provide radar measurements from tropical forest in preparation for the Biomass.
This Earth Explorer mission will provide, for the first time from space, P-band synthetic aperture radar measurements to determine the amount of biomass and carbon stored in forests.
The year-long AfriScat campaign tests this new measuring technique using a tower-based, P-band scatterometer in Ghana’s tropical rainforest.
- Characterise long-term temporal coherence at P-band (diurnal, weekly, monthly, yearly) over tropical forest.
- Identify and characterise main sources of temporal decorrelation (environmental, instrument, geometrical, structural).
- Assess 3D distribution of radar scatterers and their backscattering characteristics.
- Assess the impact of double bounce effects in the radar return of tropical forests.
- Validate simplified physical and statistical scattering models (intensity, polarimetry, polinsar) as basis for geophysical information retrieval.
