Surface-type millimeter wave scanning three-dimensional holographic imaging safety check system

Abstract

The invention relates to a surface-type millimeter wave scanning three-dimensional holographic imaging safety check system which comprises a millimeter wave signal emission driving module, a millimeter wave signal acquisition module, a millimeter wave signal processing module, a millimeter wave emission antenna and a millimeter wave reception antenna. The millimeter wave emission antenna and the millimeter wave reception antenna form a surface-type millimeter wave antenna array, wherein the surface-type millimeter wave antenna array is used for scanning a region to be detected; the millimeter wave emission antenna is connected with the millimeter wave signal emission driving module; the millimeter wave reception antenna is connected with the millimeter wave signal acquisition module; and the millimeter wave signal processing module is connected with the millimeter wave signal acquisition module. According to the surface-type millimeter wave scanning three-dimensional holographic imaging safety check system, through the surface-type millimeter wave antenna array, single scanning time is greatly reduced; and meanwhile, since equipment does need to be subjected to mechanical rotation, equipment wearing is not easy to cause, service time of the equipment is substantially prolonged and equipment fault is reduced.

Description

technical field [0001] The invention relates to a three-dimensional holographic imaging security inspection system, in particular to a three-dimensional holographic imaging security inspection system with surface millimeter wave scanning. Background technique [0002] In recent years, with the increase of terrorist incidents and the deterioration of national security issues, countries around the world have begun to pay attention to public security issues and focus on improving the effectiveness and accuracy of security detection systems. The metal security gates, X-ray detectors and infrared detectors used for public safety detection in the early days all had their own drawbacks. [0003] The active millimeter-wave scanning imaging security gate has the advantages of fast, safe, reliable, and privacy protection, and can solve the huge security loophole problem that cannot be solved by the existing general human body security check method (metal security gate). As long ...
