Embodiment Construction

[0051] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0052] At present, most of the security inspection systems used in public places are X-ray machines, which cannot perform human security inspections. Some foreign manufacturers have developed 8mm frequency human body security inspection systems, which collect data based on the movement of the turntable and one-dimensional electronic scanning, requiring personnel to be inspected Staying for a few seconds is inefficient. In addition, it is...

Abstract

The invention provides a microwave and millimeter wave human body safety check system, including a first transmit-receive array, a second transmit-receive array, a translation elevator, a mechanical motion control device, an electromagnetic wave generation device, an electromagnetic wave reception device, an array scanning control device and a master control computer. The master control computer is responsible for coordination control of a whole system and for imagery processing of three-dimension scattering information. In the safety check system, a one-dimension antenna array can complete vertical scanning, the translation elevator can complete horizontal scanning, and scanning in a range direction is performed with the combination of broadband electromagnetic waves, and thus the three-dimension scattering information can be obtained. Three-dimension imaging of a target area can be completed using algorithms of back scattering or range migration, etc. The invention utilizes the travelling translation elevator, so that the to-be-checked people stagnation condition of a rotary-type imaging system is prevented, and safety check can be completed without influencing the travelling speed.

Description

Technical field [0001] The invention relates to the field of security inspection systems, in particular to a microwave and millimeter wave human body security inspection system, and also to a microwave and millimeter wave human body security inspection method. Background technique [0002] In recent years, the international community has paid great attention to attacks by terrorist organizations. Developed countries have invested a lot of manpower and material resources in anti-terrorism. In recent years, my country has also experienced terrorist attacks from time to time, and public safety issues have gradually received attention. At present, security inspections in public places mainly rely on X-ray detectors to detect items. However, the knives, guns, explosives and other lethal weapons hidden in the clothes by terrorists can only be inspected manually, which is very inefficient and relies on simple metals. The detection rate of detector and touch inspection is not high. [000...
