Problems solved by technology

[0009] However, the existing security inspection systems are all single-switch antenna arrays. Using a single switch array antenna to scan and detect persons to be inspected prolongs the scanning time of persons to be inspected and reduces security inspection efficiency.

Abstract

The invention discloses a scanning method for a millimeter-wave active three-dimensional holographic-imaging human body security check system. The scanning method comprises the following steps: a rotary scanning and driving device is controlled by a control device to drive a first millimeter-wave switch antenna array and a second millimeter-wave switch antenna array to respectively rotate in parallel in opposite directions in a first scanning zone and a second scanning zone so as to carry out cylindrical rotating scanning to a zone to be scanned; and a parallel image processing device synthesizes the three-dimensional holographic image of a person to be detected according to the collected data from a first millimeter-wave transceiver and a second millimeter-wave transceiver and the spatial position information of the collected data.

Description

technical field [0001] The invention relates to a human body security inspection system. More specifically, the present invention relates to a human body security inspection system and scanning method based on three-dimensional holographic imaging of millimeter-wave active high-speed cylindrical rotation scanning. Background technique [0002] The urgency of international anti-terrorism has put forward many new demands on human body security inspection. First, it is necessary to be able to realize the non-undressing three-dimensional holographic imaging detection of objects covered by human clothing, so as to improve the efficiency of identifying suspicious objects; second, it is necessary to expand detection capabilities. , can detect metal and non-metal items, including guns, knives, explosives, drugs, CDs, cash, liquids, chips, ceramics, etc.; third, it is necessary to reduce the impact of detection methods on human health on the basis of ensuring the above requirements ...
