  • obtaining radar scan data comprises: obtaining frequency, amplitude, and phase scan data for one or more receiver-transmitter pairs of the ultra-wide band radar sub- systems; generating a time-amplitude plot for each of the one or more transmitter-receiver pairs; and determining a calibration point and range data to each point on the surface of the baggage from the time-amplitude plot for each of the one or more transmitter-receiver pairs.
  • the step of obtaining radar scan data comprises operating the UWB radar subsystem in a Stepped Frequency Continuous Wave (SFCW) mode.

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.
