Problems solved by technology

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

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 ...
