Résumé
Abstract

Cet article traite des campagnes de mesures radar bande X de 2006 et 2007 sur l'Aéroport Orly et juin 2008 sur l'Aéroport de Paris-CDG. Un radar Doppler bande X a été déployé pour évaluer les capacités d'imagerie à courte portée (inférieure à 2000 m) des tourbillons de sillage suivant différentes conditions météorologiques (air clair et pluie). Les données enregistrées ont été corrélées avec les modèles électromagnétiques et les modèles de mécaniques des fluides des turbulences de sillage pour une meilleure compréhension de la surface équivalente radar (SER) des rouleaux et de leur signature Doppler.

This article deals with X-band radar trial campaigns in 2006 and 2007 at Orly Airport, and in June 2008 at Paris-CDG Airport. An X-band Doppler radar has been deployed to assess short range (inferior to 2000 m) wake vortex monitoring capabilities in all weather conditions (dry and wet conditions). Recorded data have been correlated with electromagnetic and fluid mechanical models of wake turbulences for better and more accurate understanding of roll-up radar cross section (RCS) and Doppler signature.
