What was the purpose of AfriScat and AfriScat Ground?
In 2015, ESA and CNES decided to support a new experiment, based on the TropiSCAT experience, to acquire long-term P-Band radar data in an African tropical forest. The site selected to host AfriScat experiment was the Ankasa Forest Conservation Area, Ghana.
The main objectives of the TropiSCAT experiment were the temporal survey of the variation of the measurements in time scales ranging from diurnal, weekly, monthly, up to 12 months of observation. The measurements which had to be tracked are in order of priority:
- The temporal coherence in HH, VV and HV polarisations, at a very short rate in the order of 15 minutes, covering daily and monthly scale,
- The backscattering coefficient at HH, VV and HV polarisations and in all time scales
- 2D vertical imaging through tomographic focusing;
- The vertical distribution of temporal coherence, as obtained by comparing tomographic data taken at different times, covering time scales of minutes, days, and months. In addition to electromagnetic scattering measurements, ancillary in-situ data are also collected on the same area.
