Abstract

Système de réception comprenant une pluralité d'éléments de réception, écartés les uns des autres, chacun d'eux répondant à des stimuli incidents variables dans le temps pour produire un signal de sortie variable dans le temps correspondant, des moyens de traitement de signaux pour combiner les signaux de sortie des éléments de réception pour produire un schéma de réponse choisi pour les stimuli, les moyens de traitement de signaux comprenant des moyens pour soustraire les signaux de sortie d'une paire d'éléments pour obtenir un signal de différence. Le système étant caractérisé par le fait que les moyens de traitement de signaux comprennent un canal d'intégration pour intégrer le signal de différence par rapport au temps pour obtenir un signal intégré.
