Description

Notion d’onde polarisée, rectilignement, circulairement, elliptiquement.

Approche expérimentale historique depuis 1991 avec les images ERS, ENVISAT, PALSAR des observations effectuées en bande C avec les polarisations VV puis VV+VH, en bande L avec les polarisations HH puis HH+HV+VV. Intérêt de préserver la phase pour les mesures polarimétriques. Présentation de la décomposition de Pauli pour mettre en évidence, sols nus, forêt denses et forêts inondées. Exemples sur la plaine littorale de Kourou en Guyane en bande L. Comparaison avec des photographies aériennes.

Notion of polarized wave rectilinearly, circularly, elliptically.

Historical experimental approach since 1991 with the images ERS, ENVISAT, PALSAR of the observations made in band C with the polarization VV then VV + VH, in band L with the polarization HH then HH + HV + VV. Interest to preserve the phase for polarimetric measurements. Presentation of the decomposition of Pauli to highlight bare soils, dense forest and flooded forests. Examples on the Kourou littoral plain in French Guiana. Comparison with aerial photographs.
