Abstract
L'invention concerne des dispositifs de stabilisation du taux de fausses alarmes dans un radar. Le récepteur comporte un ensemble de mémoires recevant la valeur moyenne du signal vidéo de réception dans chacune des fenêtres de distance valeurs moyennes sont ensuite utilisées pour commander le gain d'un amplificateur dans la chaîne de réception en amont des mémoires et comme seuil de détection avant la visualisation. Applications aux stations radar.
