06.01.94 (19762)
ISO/IEC standard entry number
DEF

Record 2 2007-02-01

English

Subject field(s)
  • Spacecraft
  • Remote Sensing
DEF

The orientation of the radiated electric field in relation to the Earth's surface.

CONT

The relevant phase shift between the preamplifiers driven by the two antenna systems determines the ellipticity of the antenna polarization: if = 0° the polarization is linear, equivalent to a dipole tilted with respect to the spin-axis.

OBS

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

Key term(s)
  • antenna polarisation

French

Domaine(s)
  • Engins spatiaux
  • Télédétection
DEF

Orientation du champ électrique rayonné par rapport à la surface de la Terre.

CONT

La polarisation d'antenne est circulaire, la modulation se fera en FM et le ton sonore est de 1300 hertz.

OBS

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

Spanish

Campo(s) temático(s)
  • Naves espaciales
  • Teledetección
CONT

La polarización de la antena juega un papel importante en el diseño de la misma. Recuérdese que la polarización viene definida por la trayectoria que describe el vector de campo eléctrico (o magnético) cuando se observa en el sentido de propagación de la onda (la onda se aleja del observador). Así, se tiene: polarización lineal, polarización circular y polarización elíptica.
