Abstract

The invention relates to a three-dimensional holographic imaging safety inspection system and a method thereof. The system comprises a main body framework, a millimeter-wave transmit-receive module arranged on the main body framework, at least two groups of millimeter wave switch antenna arrays connected to the millimeter-wave transmit-receive module, a scanning and driving device used for driving the at least two groups of millimeter wave switch antenna arrays to rotate homonymously, a control device used for making the scanning and driving device generate a rotation angle signal and a parallel image processing module, wherein the number of the millimeter wave switch antenna arrays is the same with the number of scanning areas; and the parallel image processing module is used for synthesizing a three-dimensional holographic image of a tested object according to an echo signal collected by the millimeter-wave transmit-receive module and space position information corresponding to the echo signal. By using the system and the method, a system structure is simplified and acquired imaging resolution is high.

Description

technical field [0001] The invention relates to the technical field of millimeter wave imaging, in particular to a security inspection system and method for three-dimensional holographic imaging. Background technique [0002] Millimeter waves have frequencies from 30GHz to 300GHz (wavelengths from 1mm to 10mm). In the electromagnetic spectrum, the position of millimeter wave frequency is between infrared and microwave. The millimeter wave imaging system mainly has the following characteristics: it is sensitive to the shape and structure of the target, and has a strong ability to distinguish metal targets from the background environment; the obtained image has high resolution, so it can improve the ability to identify and detect targets; compared with infrared laser , millimeter waves are less affected by harsh natural environments, and can be used in harsh environments such as smoke, clouds, and fog; the system is small in size and light in weight. Compared with microwave c...
