Abstract

L'invention concerne les circuits éliminateurs d'images parasites. Elle se rapporte à un circuit qui comprend des lignes de détecteurs 10, 12, 14,.. reliées à des positions de bit 16, 18, 20,... d'un registre 22, et les sous-trames successives qui se trouvent dans des positions successives permettent la formation à la sortie d'une différence représentant les images parasites. Application au traitement des signaux des radars.The invention relates to parasitic image elimination circuits. It relates to a circuit which comprises lines of detectors 10, 12, 14, .. connected to bit positions 16, 18, 20, ... of a register 22, and the successive subframes which are found in successive positions allow the formation at the output of a difference representing the parasitic images. Application to the processing of radar signals.
