CNES/
DTQTIS


Customer: Centre National d’Etudes Spatiales (CNES)

Programme: DTQTIS

Supply Chain: CNES > CS Group SPACE

Context

CS Group responsabilities for Polarization calibration on natural sites are as follows:

  • Study

Main Picture

The features are as follows:

  • Polarized signal sensitivity analysis :
  • Estimation of dissemination orders contributing to the polarized signal to the TOA
  • Influence of the aerosol model
  • Influence of surface properties (BRDF, refraction index)
  • Influence of aiming and AOT geometry
  • Parametric analysis Representativeness of BPDF models on desert sites :
  • Comparison of measurements and models for different BPDF models
  • Analysis of the Inversion results of the Maignan model weighting coefficient

Project implementation

The project objectives are as follows:

  • Characterize the surface polarization of desert sites (BPDF) in order to make an absolute calibration on polarized bands (Mission 3MI)

The processes for carrying out the project are:

  • Studies, simulations, advancement meetings, report

Technical characteristics

The solution key points are as follows:

  • Incommensurate
