Subject field(s)
  • Remote Sensing
DEF

[A signature that] draws the scattering coefficient as a function of any assumed transmit and receive antenna polarization, allowing the measurement of the variation of the scattering coefficient with polarization.

CONT

Radar polarimetry allows the identification/interpretation of scattering mechanisms in natural media by employing differences in the polarisation signature for purposes of classification and parameter estimation.

OBS

polarisation signature: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG).

French

Domaine(s)
  • Télédétection
DEF

[Signature qui] décrit le coefficient de rétrodiffusion en fonction des paramètres de polarisation pour n'importe quelle configuration d'antenne, [ce qui] permet d'évaluer le taux de variation de la rétrodiffusion relativement à la polarisation.

OBS

La polarimétrie radar permet l'identification et l'interprétation des mécanismes de diffusion de milieux naturels grâce aux différences entre les signatures de polarisation et ce, à des fins de classification et d'estimation de paramètres.

OBS

signature de polarisation : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).
