Abstract
a. Radar à pulsations, en particulier radar de Doppler à pulsations avec des voies de distance, avec emploi de démodulateurs et de dispositifs d'intégration branchés en aval, qui additionnent les signaux d'écho venant d'une cible et les transmettent pour indication. b. Radar caractérisé en ce que pour la supression de perturbateurs en forme d'impulsions, avec une durée des signaux perturbateurs petite en comparaison du temps de balayage et avec une amplitude grande en comparaison des signaux d'écho de la cible, il est prévu un dispositif de différentiation au moyen duquel la montée brusque des signaux perturbateurs est arrêtée et pour une partie de la durée du signal perturbateur l'intégration est empêchée dans le dispositif d'intégration. c. Radar applicable à une écoute à distance en vue d'atténuer les perturbations en forme d'impulsions.
