Abstract

The invention belongs to the synthetic aperture technology field, and discloses a synthetic aperture technique-based millimeter-wave video imaging system and a method. The system comprises a data acquisition device and a data processing device. The data output end of the data acquisition device is connected with the data input end of the data processing device. The data acquisition device comprises an annular scanning track and a radar arranged on the annular scanning track. The radar adopts a single-input and single-output channel and is in the form of a millimeter-wave radar. The system adopts the single-channel millimeter-wave synthetic aperture radar imaging technology, and is configured to run on the annular track. Therefore, the video imaging can be realized within a plurality of frequency bands. The advantages of short imaging time, high image resolution, high recognition rate, intuitive and natural recognition and the like are realized. The security check efficiency can be improved, and the geometric structure is simple. The cost is low. As a result, a lot of manpower and material resources can be saved.

Description

technical field [0001] The invention belongs to the technical field of synthetic aperture, and in particular relates to a millimeter-wave video imaging system and method based on synthetic aperture technology. place. Background technique [0002] With the continuous escalation of international terrorist activities, the security situation has become more and more severe. Security issues at customs, airports, railway stations and other public places with frequent population gatherings have received extensive attention from all over the world. Therefore, human security screening in important transportation hubs including airports and important places such as government offices has become an important issue. essential work. [0003] Traditional security detection systems for human body mainly include metal detectors and millimeter wave imaging for human body detection. The commonly used measure in China is to use metal detectors, while foreign security inspection systems mainl...
