Problems solved by technology

[0003] Among the active millimeter-wave 3D holographic imaging technologies used in human body security inspection, cylindrical scanning imaging technology is widely used, but its equipment is bulky and its algorithm is complex, and its algorithm is obtained after approximate processing in theory , so the imaging accuracy cannot be guaranteed
In addition, cylindrical scanning can only use a vertical antenna array, which is longer and has more antenna units, which greatly increases the cost of the equipment

Abstract

A millimeter wave three dimensional holographic scan imaging apparatus and a method for inspecting an object to be inspected using the same are disclosed. The apparatus includes a millimeter wave transceiver module with a millimeter wave transceiver antenna array for transmitting and receiving a millimeter wave signal. The apparatus also includes a guide rail device, to which the millimeter wave transceiver module is connected in slidable form. The millimeter wave transceiver module is moveable along the guide rail device to perform a plane scan on an object to be inspected. A data processing device generates a millimeter wave holographic image from the plane scan.

Description

technical field [0001] The invention relates to the technical field of human body security inspection, in particular to a millimeter-wave three-dimensional holographic scanning imaging device and an inspection method for inspecting an object to be tested by using the millimeter-wave three-dimensional holographic scanning imaging device. Background technique [0002] Currently, the most widely used security inspection technologies for imaging objects such as human bodies or articles are mainly X-ray imaging technology and millimeter wave imaging technology. Millimeter wave imaging technology is increasingly recognized by the market. Millimeter wave imaging technology is mainly divided into passive millimeter wave imaging technology and active millimeter wave imaging technology, and active millimeter wave imaging technology is mainly holographic imaging technology. [0003] Among the active millimeter-wave 3D holographic imaging technologies used in human body security inspec...
