Real time imaging by antenna and hybrid device

Abstract

We propose, for localisation of acoustical sources and imaging, an hybrid proceeding working in real time . From array antenna signais we make a spatial transversal filter with analog and digital electronic devices : speed is assumed by the analog part and accuracy of angular pointing or focalisation by the digital part .On propose de localiser des sources acoustiques et d'en former une image par une méthode de traitement hybride opérant en temps rée
