Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] It should be noted that when an element is referred to as being “fixed” or “disposed on” another element, it may be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0035] It is to be understood that the terms "length", "width", "top", "bottom", "front", "rear", "left", "right", "vertical", "horizontal", "top" , "bottom", "inner", "outer" and other indicated orientations...

Abstract

The invention provides a safety detection system and method for millimeter-wave real-time imaging. The safety detection system comprises a transmission device, a millimeter wave transceiver module, an antenna array, a switch array, a switch control unit, a quadrature demodulation and data acquisition module and an image display unit. By adopting an inverse synthetic aperture radar (ISAR) imaging principle, through the adoption of the safety detection system for millimeter-wave real-time imaging, real-time imaging is conducted when an object to be detected moves, the imaging speed is increased, the field of view is enlarged, security personnel can judge whether or not a detected person carries dangerous objects by observing a three-dimensional diagram of the body of the detected person, and therefore the inconvenience caused by back-forth movement of security equipment used by the security personal on the body of the detected person is eliminated.

Description

technical field [0001] The invention belongs to the field of security inspection systems, and more specifically relates to a millimeter-wave real-time imaging security detection system and a security detection method. Background technique [0002] In recent years, security issues have increasingly attracted the attention of people all over the world, and higher requirements have been put forward for the reliability and intelligence of the security inspection system. [0003] Traditional metal detectors can only detect short-distance and small-scale targets, and their efficiency is low, which is far from meeting the needs of security inspections. Although various rays such as X-rays have strong penetrating power, they will cause radiation damage to the human body under test. Even if X-ray machines with low radiation doses currently exist, they are still not easily accepted by the public. Infrared rays are imaged by the surface temperature of objects, and cannot be clearly im...
