sigma zéro

Désignations

français	sigma zéro (correct,masculine noun,officially approved) OBS: sigma zéro : terme uniformisé par le Groupe de travail de la terminologie de RADARSAT-2 (GTTR).
anglais	sigma naught (correct,officially approved) OBS: It is a normalized dimensionless number, comparing the strength observed to that expected from an area of one m². Sigma naught is defined with respect to the nominally horizontal plane, and in general has a significant variation with incident angle, wavelength, polarization, as well as with the properties of the scattering surface itself. OBS: sigma naught: term officially approved by the RADARSAT-2 Terminology Approval Group (RTAG). synonyme : sigma 0 (correct)
