Embodiment Construction

[0050] The preferred implementation examples of the present invention are given below in conjunction with the accompanying drawings to describe the technical solution of the present invention in detail.

[0051] Such as figure 1 As shown, a millimeter-wave mechanical scanning human body imaging security inspection equipment uses a pair of horizontal detection arrays to scan vertically. The system consists of a pair of in-line detection arrays 1, a signal acquisition and processing unit 2, an imaging processing unit 3, a control display unit 4, Scanning unit 5 (including servo control 6, traction machine 7, traction rope 8, guide wheel 10, etc.) and power supply unit 9 are composed of parts. The inspected person enters the security inspection gate, stands facing forward at the designated position and raises his arm to keep still. The operator sends a scanning command through the control display unit, and the scanning servo mechanism drives the left and right detection arrays to...

Abstract

The invention belongs to the technical filed of security inspection and relates to a vertical mechanical microwave scanning active imaging personnel security inspection system. By means of creative design and through adoption of a pair of horizontal detection arrays which are separately arranged in parallel on two sides or the front side and the back side of an inspected person in a vertical mode, vertical scanning imaging for the inspected person is conducted. Each detection array is in a shape of a straight array or a bow shape with two inwards folded heads or an arc shape or the like. Compared with an existing adopted vertical detection array active imaging personnel security inspection system, the vertical mechanical microwave scanning active imaging personnel security inspection system has the advantages that the number of transmit-receive components of the detection arrays can be reduced greatly and a system structure is simplified. Not only is convenience brought to storage, transportation, installation and usage but also system cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of security inspection and relates to a personnel scanning imaging security inspection system. Background technique [0002] The present invention utilizes micro-waves (such as millimeter waves) that are safe to the human body and can penetrate clothing made of normal materials but will be reflected (scattered) by other higher-density objects to scan and image personnel to obtain the surface of the human body and the objects on the surface of the body. Video, imaging inspection of carry-on items, to achieve the purpose of non-contact "see-through" security inspection of personnel. [0003] At present, this type of imaging security inspection system uses a vertical detection array for horizontal arc-shaped mechanical scanning or a phased array antenna array for electrical scanning. The system takes up a lot of space, and it is inconvenient to store, transport, and install, and the cost is high. Contents of ...
