Abstract

L'INVENTION CONCERNE UN RADAR DOPPLER COHERENT A IMPULSIONS. SELON L'INVENTION, LES IMPULSIONS SONT EMISES SELON UNE FREQUENCE DE B TRAINS D'IMPULSIONS RECURRENTES. LES FREQUENCES DE REPETITION , FR1, FR2, FR3 ETC., SONT DIFFERENTES D'UN TRAIN D'IMPULSIONS A UN AUTRE ET LES B TRAINS SONT EMIS SIMULTANEMENT DE TELLE MANIERE QUE DEUX IMPULSIONS DE DEUX TRAINS DIFFERENTS NE PUISSENT ETRE EMISES EN MEME TEMPS. LA PRESENTE INVENTION S'APPLIQUE DANS LE DOMAINE DES RADARS DOPPLER.
