Abstract

L'invention concerne un montage pour réaliser la conversion série-parallèle de signaux de réponse dans des systèmes de radars secondaires. Dans ce montage la largeur des impulsions de signaux de réponse est normalisée dans un circuit d'entrée 1, puis les impulsions sont introduites dans une ligne à retard numérique 2 pouvant recevoir deux télégrammes d'impulsions et comportant des prises espacées suivant une trame correspondant aux écarts entre les impulsions du télégramme, et sont exploitées dans un système d'analyse vidéo 3. Application notamment aux radars secondaires de surveillance.The invention relates to an arrangement for performing serial-to-parallel conversion of response signals in secondary radar systems. In this arrangement, the width of the response signal pulses is normalized in an input circuit 1, then the pulses are introduced into a digital delay line 2 which can receive two pulse telegrams and comprising taps spaced along a frame corresponding to the differences between the pulses of the telegram, and are used in a video analysis system 3. Application in particular to secondary surveillance radars.
