three antennas a fore-beam - mid-beam -

instrument will yield wind vector measurements in
50 km resolution cells. It will be capable of
measuring wind speeds in the range 4  24 m/s
with an accuracy of 2 m/s or 10 and wind
direction in the range 0 360 with an accuracy
of 20. On an experimental basis, the instrument
will provide measurements at an enhanced
resolution of around 25 km.

altimetry (1) L'altimétrie spatiale est une
technique permettant de mesurer des hauteurs par
satellite. Elle utilise le temps mis par un
faisceau radar pour faire l'aller-retour
satellite-surface, associé à une localisation
précise du satellite, pour effectuer ses mesures.
Principe de l'altimétrieL'altimètre émet une
onde radar et l'analyse après réflexion sur la
surface. La hauteur de mer est égale à la
différence entre la distance satellite - surface
(déduite du temps mis par l'onde pour faire
l'aller-retour) et la position du satellite par
rapport à une surface de référence arbitraire
(l'ellipsoïde de référence). Des systèmes de
localisation comme Doris permettent une précision
extrême sur cette position du satellite en
orbite. Il faut aussi tenir compte de la moindre
perturbation subie par l'onde radar. La mesure de
ces perturbations (par des instruments annexes,
ou par l'utilisation de plusieurs fréquences), ou
leur estimation par des modèles, permet de
corriger la mesure altimétrique.
