Abstract

La présente invention concerne un système d'inspection par balayage de bagages comprenant : une ouverture délimitant un tunnel d'inspection par balayage ; un convoyeur se déplaçant à travers le tunnel d'inspection par balayage, un bagage inspecté par balayage se déplaçant sur le convoyeur ; un réseau radar UWB entourant l'ouverture pour fournir des données d'inspection par balayage radar correspondant au bagage ; un réseau LCMD positionné à un emplacement autour du bagage permettant d'obtenir des données d'inspection par balayage LCMD correspondant au bagage ; et au moins un processeur pour corréler les données d'inspection par balayage radar et les données d'inspection par balayage LCMD pour fournir une ou plusieurs régions suspectes mises en évidence sur une image vidéo du bagage qui est inspecté par balayage.
