Title (EN) MTI-FILTER IN A TRACKING RADAR RECEIVER
(FR) FILTRE MTE DANS UN RECEPTEUR DE RADAR DE PISTAGE
Abstract: front page image
(EN)An MTI-filter included in the receiver part of a tracking radar for suppressing clutter when receiving echo pulses from a certain target. The transmitting pulses of the tracking radar are transmitted in series where the carrier frequency is varied from pulse to pulse and is repeated from series to series. The MTI-filter (F) contains a number of delay links (DL1-DLN), for example digital shift registers which are stepped forward timely with the radar PRF. The input of the filter and the output of the shift register M(Alpha)N are connected to a differentiator (SK) where M = the number of carrier frequencies in a pulse series.
(FR)Un filtre MTI (indication de cible mobile) incorpore dans le recepteur d"un radar de pistage supprime l"encombrement lors de la reception d"impulsions d"echo provenant d"une cible. Les impulsions de transmission du radar de pistage sont transmises en serie la ou la frequence porteuse varie d"impulsion a impulsion et elle se repete de serie en serie. Le filtre MTI (F) contient plusieurs maillons de temporisation (DL1-DLN), par exemple des registres a decalage numerique qui avancent pas a pas en synchronisation avec le radar PRF. L"entree du filtre et la sortie du registre a decalage M(Alpha)N sont connectees a un differentiateur (FK) ou M = le nombre de frequences porteuses dans une serie d"impulsions.
