Automatic non-destructive insight obtaining method for luggage inspection, involves displacing radar emitter relative to box over two-dimensional aperture, and supplying beam response of signal processing for displaying content in box

摘要

#CMT# #/CMT# The method involves illuminating a non-metallic closed box (1) with a radar emitter (3). The emitter is displaced relative to the box over a two-dimensional aperture. A beam response of signal processing is supplied for displaying content in the box using a display (5). Analog measuring signals are filtered, amplified and stored in a digitized manner. Distribution of reflectivity of a scene is computed over signal runtime. A three-dimensional scatter center distribution of a spatial area is emitted according to a principle of a synthetic aperture using a polar reformatting algorithm. #CMT# : #/CMT# An independent claim is also included for a device for executing a method for obtaining automatic non-destructive insight in a non-metallic closed box. #CMT#USE : #/CMT# Method for obtaining automatic non-destructive insight in a non-metallic closed box for luggage inspection (claimed) to test content e.g. weapon and explosive, in the box. Can also be used for a case, package or luggage piece in safety-critical areas e.g. airport, railway station and customs station. #CMT#ADVANTAGE : #/CMT# The beam response of the signal processing is supplied for displaying the content in the non-metallic closed box, thus enabling automatic non-destructive insight in the non-metallic closed box in a safe manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block representation of a testing device. 1 : Non-metallic closed box 2 : Positioner 3 : Radar emitter 5 : Display 6 : Input interface.
