Abstract

L'invention concerne un procédé de traitement des données d'un radar de navigation Doppler aéroporté pour déterminer la vitesse de l'aéronef. Les données d'échos du canal de différence de trois faisceaux formés successivement sont tournées d'un angle assurant que le zéro du diagramme de différence associé avec chacun des trois faisceaux reste parallèle à un lieu déterminé de décalage Doppler constant. Les données sont ensuite normalisées avec les données du canal de somme, puis elles subissent un traitement pour déterminer la fréquence Doppler associée au zéro de chacun des trois faisceau. La données de fréquence sont ensuite converties en données de vitesse et sont combinées avec les données d'une plate-forme à inertie. Application à la navigation aérienne.
