Abstract

The invention discloses a scan method of a human security system utilizing frequency division technology to avoid opposite radiation interference. The method comprises that in a scan period, at a same time, work frequency of detection signals which are provided by a first millimeter wave transceiver and a second millimeter wave transceiver are different. According to the invention, opposite radiation interference of two sides switch antenna arrays of a millimeter wave active three-dimensional holographic imaging human body security system is avoided, and an imaging sharpness level is raised.

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 ...
