Abstract

Senseur d'alarme par intrusion pour détecter la présence d'une cible en mouvement, en présence de phénomènes stationnaires ou périodiques interférents avec ladite cible Ce senseur comprend un dispositif générateur d'oscillations d'une fréquence déterminée, un dispositif transducteur accouplé au générateur pour transmettre ces oscillations impulsées, un transducteur de réception des ondes de retour impulsées, un mélangeur produisant des signaux décelés par impulsions et transportant une information Doppler, un dispositif d'élaboration de signaux impulsés de cette information, ainsi qu'un système de démodulation fournissant en sortie des signaux d'alarme.
