Abstract

L'invention concerne les radars Doppler émettant des impulsions par bloc à différentes fréquences d'émission et de répétition. Selon l'invention, il est prévu d'émettre entre les blocs d'impulsions, une impulsion unique à une fréquence différente de celles des blocs adjacents. A cette impulsion unique correspond une voie d'analyse particulière dont la sortie est utilisée pour corriger éventuellement les décisions prises au niveau du traitement effectué sur les blocs. L'invention s'applique dans les radars Doppler à diversité de fréquence.
